I'm a believer that multiple competing things can be true at the same time. That said...
-Every service called out the OL, and it bears out via stats.
-Every service called out Narduzzi for calling a great game plan. Every service said the blitzes were well timed, well disguised, and were almost, if not more common than not blitzing. Every service called out great coverage by Pitt's DBs.
-While Book could have trusted the pocket more at times, there were enough times he could not trust the pocket to make him question protection.
-Book wasn't the only one that did not trust the pocket, or the line in general. Play calling made that clear. Lack of run calls, play calling to move the pocket, play calling to start drives in the second half series to attack the edges in the rushing game.
-Book, while he took some sacks, also had the longest rush of the day, and I believe 2 or 3 of the top 5 rushing attempts. He only took 3 sacks, which IMO was decent given what Narduzzi was throwing him. The first big one is debatable as the right side was collapsing, and the left side broke containment early. One of the others was almost immediate penetration.
-Book threw 2 INTs. The first one was on him, the second was not. The second he was hit on the arm while in motion. If not hit, he would have likely hit the WR for a TD over the middle.
-I look at Book for what he is, and what we know he is good at. He's good at short to intermediate (he's improving as we saw with the long ball). He was starting his 4th game, never seeing a Narduzzi like attack. He wasn't perfect early, but adjusted. He was not however "bad" given the protection, and what Narduzzi was calling.
-His QB Rating (159) for that game was more than decent. 159 is still a top 25 average (QB Rating leaders for the year). His QBR sucked, but QBR is also detrimental to QBs who are short to intermediate passers, and very detrimental to QBs who have struggling OLs.
-Would love to read what Driskell said, but don't have Rivals. Driskell is a turd, don't really agree on much he says, and my least favorite (I think this a popular view). And lastly, Driskell is the same guy who talked about the OL regressing so much (like several others). And I think he was also the biggest BW apologist out there (at least the pre-season stuff I read).
Anyway.... if you agree the OL has major problems (which are evident to the eye, and advanced stats), agree Narduzzi called a hell of a game both blitz and coverage (which everyone has said), embrace the good stats (completion %) as much as the negs (sacks/Ints), and not fault a 4 game starter vs an exotic D for hitting his first read instead of holding and going through progressions... it's hard for me to say he was that "bad", even in the first half. All that is enough for me. I get it, you see it another way, and that's OK.
