lol @ invoking 'what the professionals say.' Frankly I give more credence to your fan's opinion. Regardless of whether these guys are former professional players, coaches, whatever, that isn't what they are now. They're professional content providers. They go up there and word vomit empty cliches to kill time. None of this is actual shop talk. Not even when they get rid of the anchor, lose the jackets and ties, and sit in a circle with their elbows on their knees. You ever catch that one? The networks both rolled out basically identical updates on the Retired Pros Just Sitting Around Talking About The Game show this season. NFLN is always hacky but with ESPN this stuff is shades of Olbermann in a bomber jacket. As fans go I have little doubt that an EY production would at minimum be a little less insulting to my intelligence.
'What the professionals say' about the quality of coaching Sanchez has received is the demonstrated market for Schottenheimer's services. He has been kept on by the Jets through a head coaching change and subsequently extended, with persistent interest from the rest of the league, specifically and tellingly including both of the other two teams in our division not coached by Bill Belichick and both of the other two teams that drafted starting quarterbacks in the first round in 2009.
At the end of the day it doesn't really matter all that much who the offensive coordinator is. From 'play design' -- I always picture Schottenheimer furiously scribbling on a chalkboard like Damon in Good Will Hunting when I hear that -- to in-game calls to the teaching points you mentioned earlier, this stuff is all a matter of best practices, and not even the least competent NFL coach is oblivious to things that seem obvious to morons on couches.
