Alright, I put on the replay and isolated on Joe every play.
Here is what I saw:
JOE ISO
FIRST DRIVE
Play 1 (1st and 10): Joe sticks his nose into the hole and takes on a blocker. Doesn’t make the tackle, but does a good job of attacking the running lane. Just a good 5-yard power by Pitt. EVEN.
Play 2 (2nd and 5): Joe fills the first lane that develops to the right on another run play, takes on a block very quickly in the hole, forces runner to pick different lane. Jaylon fails to fill the next void that opens, Pitt picks up a first down. +1.
Play 3 (1st and 10): Pitt fakes a run to the right and tosses left. Joe is initially fooled and hesitates, but makes up the ground to the edge and gets involved with the tackle. A nice recovery by several defenders holds it to five yards after some space seemed to exist initially. +1.
Play 4 (2nd and 5): Joe dips underneath a block on another run to the left outside. Non-factor, as the edge defenders made a nice play to string it out for a small loss. EVEN.
Play 5 (3rd and 7): Joe shows blitz, then bails out into what looks to be a flat zone or a buzz zone underneath of safety help. Takes the slot receiver away as the receiver moves through his zone by staying in the throwing lane. Pass complete on the outside for a first down with KVR in coverage. +1.
Play 6 (1st and 10): Joe takes on a block in the hole on a power run, doesn’t give up much ground, involved in gang tackle after a 5-yard gain. EVEN.
Play 7 (2nd and 5): Joe again takes on a block in the hole, this time he gets swallowed up and pushed back as a gang tackle occurs after a 4-yard gain. -1.
Play 8 (3rd and 1): Pitt calls an excellent PA fake, their QB roles out into all of the green grass. Joe was fooled like the rest of the defense and collapsed on the fake. Just a good play-call by Pitt to the weak side. EVEN.
Play 9 (1st and goal): Pitt now at the ND 7. Stretch play to the left, Joe takes on a blocker and gives up some ground, defeats the block and would be in position if needed, but the ballcarrier is dropped short of Joe for a 3-yard gain. EVEN.
Play 10 (2nd and goal from the 4): Pitt throws a fade at the snap, nothing to see. EVEN.
Play 11 (3rd and goal from the 4): Joe does a reallllly nice job of locating the crossing receiver and trailing right on his hip. Pitt QB has to scramble, but the receiver was eliminated from the play even if the pocket was good. Good work Joe. +1.
SECOND DRIVE
Play 1 (1st and 10 at the Pitt 19): Joe gets caught in traffic on a basic slam play up the middle, can’t get to the outside when the RB moves that way. Trails the play, but not a bad play. EVEN.
Play 2 (2nd and 5): PA fake that Joe bites on, but clears out pretty quickly into his pass responsibility. ND forces a throw-away. EVEN.
Play 3 (3rd and 5): Joe is in great coverage on JP Holtz, right on his hip. The throw and catch need to be perfect; they are NOT perfect. Excellent job by Joe. +1.
THIRD DRIVE
Play 1 (1st and 10 at the Pitt 30): PA fake with what looks to be only one receiver running, incomplete deep. EVEN.
Play 2 (2nd and 10): A fake toss with a handoff back to the left. Joe recognizes the fake and takes a deep angle to try and get across the field, but isn’t needed. Holding called on the play. EVEN.
Play 3 (2nd and 20): A handoff up the middle. Joe takes on the block and doesn’t give up ground, kind of helps with the tackle. I’ll allow it. +1.
Play 4 (3rd and 17): Joe sit underneath in pass coverage, picks up the RB out of the backfield. The RB shakes Joe and would have had a catch and some yardage, but the QB misses the throw. Tough open-field coverage matchup, but you can’t fall for the hip fake. -1.
FOURTH DRIVE
Play 1 (1st and 10 at the Pitt 28): Toss to the outside. Joe fights through traffic and takes a deep angle. Not his responsibility to make a play on this one. 9-yard gain. EVEN.
Play 2 (1st and 10): Joe takes on a block, locates and catches the RB as the OL tries to get to the second level, minimizing the gain. A first down, but Joe played it well. +1.
Play 3: (1st and 10): PA fake, and Pitt has two offensive lineman way too far down field. Ball is caught but eventually overturned to incomplete.
Play 4: (2nd and 10): Joe diagnoses a WR screen, goes unblocked, and has the WR lined up for an easy tackle. Joe whiffs, and he wasn’t even going for a kill-shot. This one is bad. -2.
Play 5: (3rd and 1): Joe attacks the hole in short-yardage, brings some noise and helps stop the RB short. +1.
Play 6 (4th and short): Joe helps fill again, does a nice job of fighting through a block and hitting the RB in the backfield for a solo tackle. Though the RB did a nice job of spinning and falling forward for a first down (by inches), good play by Joe. Couldn’t do it much better. +1.
Play 7 (1st and 10): PA to the TE on a corner, not Joe’s side. EVEN.
Play 8 (1st and 10): Joe runs with the RB out of the backfield on a go-route. Joe is a few steps behind, but he has safety help over the top, so the QB would have to make a perfect throw over the top as Joe trails. Matthias gets the pick. Joe was beat, but the tight field allowed Farley to make the play while Joe was technically preventing a short throw. EVEN.
FIFTH DRIVE
Play 1 (1st and 10 from the Pitt 36): Joe clears out against a pass, sitting underneath the corner/safety who were both in coverage on receivers. Wasn’t tested as Onwualu gets a sack. EVEN.
Play 2 (2nd and 17): JP Holtz drops a pass as Joe cleared out to help immediately. EVEN.
Play 3: (3rd and 17): Joe tries to blitz along with Jaylon and James as BVG brings the house. Joe is nullified by a guard immediately, doesn’t even make a move to avoid or get off of the block. Pass complete, but short of the first down. -1.
SIXTH DRIVE
Play 1 (1st and 10 from the Pitt 16): Joe has RB responsibility in pass coverage. The RB wheels to the flats, Joe follows. The QB takes off, and Joe peels back to attempt a diving tackle. He misses, but actually did an okay job of just getting back involved when the DL lost lane integrity. EVEN.
Play 2 (1st and 10): Joe is once again settled in the middle in pass coverage, but Pitt attacks deep while the RB stays in. EVEN.
Play 3 (2nd and 10): Joe shows blitz, retreats to the seam. Throw goes to opposite side. EVEN.
Play 4 (3rd and 10): Joe blitzes as BVG brings the house once again. He comes free as the unaccounted man, but Peterman outruns him to the edge. Your MLB NEEDS to make this play. HOWEVER, Peterman was surprisingly athletic, and Jaylon is the only LB on this team that would have actually made the play because of Peterman’s recognition/athleticism to the edge. If Peterman doesn’t immediately feel the pressure, Joe probably gets home. EVEN.
What did I learn from ONE HALF (keep that in mind lol) of isolating on Joe?
1. Pitt was not picking on Joe. That's why there are so many plays marked as "EVEN," and not "+1" or "-1"
Pitt was picking on the secondary, as others have said. The secondary was actually helped out by some poor throws, drops, and some pressure from ND's front 7.
2. Joe makes as many "okay" plays as he makes "not great" plays, so there was I think a pretty even distribution of +1's and -1's.
3. Joe doesn't make many boom plays, because he lacks athleticism. He has more potential for big bust plays, which we saw one of in the first half (I know there is another in the second half, but I didn't break that down).
4. Joe was +4 in the first half according to my crude grading/judgement scale. Of course, I don't know his actual responsibilities, so I might be way off. However, it seems pretty clear at the snap that Joe is in command of the mental aspect of the game, because his responsibilities at least seem very clear to me, someone without any actual coaching/scouting experience. I tried to be impartial, but I fear I may have erred on the side of positivity. Some of those EVENs might be -1's in someone else's eyes.
In conclusion, Joe is not enough of a liability to warrant as much griping as we do, I don't think. I will try, personally, to refrain from pointing out every play he doesn't make.
HOWEVER, I think it's also clear that your MLB at this level of football needs to be able to turn some "EVEN" plays into "+1" plays, and some "-1" plays into some "EVEN" plays using his athleticism. Joe just lacks the tools to make this happen.
Another point is that if Joe is truly in charge of communication, it's not making much of a difference in terms of the front 7, because those guys all do a good job of flowing and playing their assignments. The problems are in the secondary, and if Joe's communication skills aren't helping that anyway, why not at least give some reps to younger guys in the middle here and there?
TL;DR
Joe isn't as bad as the complaining seems to illustrate, but his level of play also shouldn't really be acceptable for a starting MLB at ND. He is actually pretty good in coverage, but lacks the ability to make things happen on his own.
