Agree. I'm not football savvy enough to see if Lamar was missing his quicker reads or whether they were covered as well. Hard to believe that a coach of Petrino's caliber wouldn't have started to make SOMETHING available on a shorter route.
If options were available and Lamar was just missing them too many times, that's a greater concern at the end of his second season. He wasn't consistently getting enough time to handle his QB responsibilities in the pocket, but he also wasn't taking advantage of the opportunities he had. Or at least that's the way it appeared.
I don't think Petrino is simply covering for his O-line when he says that 11 guys plus the coaching staff are responsible when the QB gets sacked or hurried. The game's more complex than some of us try to simplify it to be. And on last reports, we have the best guy in the biz to get it figured out for the offense. Hell, he just has to get it back to where it was a couple months ago...
