This is generally a very good post, but the ultimate conclusion and some of the bolded is very questionable.
1) NFL draft picks and the general amount of talent placed in the NFL tells a different story about "player development" . Harrison Smith raved about his coaching. Same with Will Fuller. Same with a lot of players. ND has put more talent in the NFL under Kelly than all but a few schools. Players are being developed, and being developed on both sides of the ball.
2) Kelly has never been reluctant to play young players. BVG was reluctant to play guys he didn't "trust" and Kelly has made a conscientious move to correct this issue. In fact, he talked about it at length after firing BVG and proof has been in the pudding. Under Diaco this was never the case (see Farley and KVR staring in 2012 on defense with no experience). And it's not been the case on offense. You could make stronger argument that he should be red shirting more guys (see: Okwarax2) than that he "isn't playing young guys." Really, there are only a handful of examples him sticking with an "under performing veteran" and they're almost exclusively on defense under BVG with Joe Schmidt being the one everyone points to.
3) Some people might legitimately be turned off by Kelly's antics in the USF game (he hasn't gone "red face" in 5 years) and by his general coaching style. This is legitimate. But Harbaugh and Saban... who will sign the top two classes this year... are 10x worse, and they still get it done on the trail. So I don't really buy that it's a huge issue.
4) Notre Dame's graduation rates obviously destroy the argument that average kids "can't make it at ND," so there's really no point discussing this. If a recruit is "questioning" that, then they're an idiot. Every school has academic attrition, we just pay attention to ours more closely.
5) The idea that there are tons of high star guys ready to play and not being given the opportunity
for no reason is just a fallacy. People look at the Nyles Morgan situation as proof of this, but he's the exception not the rule. Jay Hayes vs Trumbetti... well, Trumbetti was a 4

too and people were complaining that he wasn't playing more behind Okwara (who was simply much better and an NFL caliber player). Sometimes there's a reason someone is sitting. Same with people calling for Redfield over FArley cuz Refield had the stars... guess which one is in the NFL getting snaps and which one is on the street with seemingly no future. And with Hayes, again, Kelly moved to correct that once he ditched BVG. Again, looking at 7 years of results proves this isn't the case overall. Lynch, Tuitt, etc. got reps immediately after getting on campus. Fuller got reps as a frosh. They went to more talented Golson as a RS frosh in 2012 over more experienced Tommy Rees strictly on upside/arm talent.
5B) Wimbush got reps as a true frosh. QBs usually take at least a RS year at every major program. DeShone Kizer was the returning starter coming off a 10 win campaign and was pilled as a top NFL draft pick. There is literally no kid that will look at a (happy) Brandon Wimbush who has the opportunity to be a 3 year starter and say "oh my gosh they did him wrong!" This displays a fundamental misunderstanding of how college QBs are groomed if there is someone good ahead of them. At the point where the team committed to Kizer, they had to sit Wimbush this year to preserve that year of eligibility. Anything else would be malpractice for both him and the team.
6) For the majority of Brian Kelly's tenure, the defense has not been a "failure." It has been a failure for the past 3 seasons. Part of that is recruiting... which is a chicken & egg kind of the thing. If Diaco and Cooks and BVG had recruited harder, then we wouldn't have been stuck with so many roster holes and having to go with the youth movement. If the scheme wasn't terrible under BVG, then the defense would've produced better and it would've been easier for him to attract recruits. No recruits right now care about that past, though. They're waiting to see who the DC hire is. They're looking at early PT... something you're saying doesn't exist, despite the fact that there is a massive youth movement on that side of the ball... and they're looking at player development. If you're a defensive recruit, you'd be foolish NOT to look at Notre Dame if your goal is to get PT and get to the NFL. Or you're interested in an elite education. Or (insert a number of other attractive aspects)... as long as the DC is someone you believe in, and that DC is a good salesman. There was a serious issue under BVG of many players questioning whether they were being put in a position to succeed that did not exist under Diaco/Cooks/Elliot/Elston. The new staff... whether or not Lyght, Elston, or Gimore is retained... has to re-establish the credibility Notre Dame had for the first four years under Kelly.
