Tough for me to complain since I didn't see the game but I do wonder about the comments about Blake not handling the blitz. I think your statement that you can't blame it on the WR's to an extent is wrong, you absolutely can. Look at how many times this year on blitzes we've wound up with the ball going one way and teh WR the other, either Blake is terrible at hot reads, or his WR's are. Given how they keep starting Blake, and both Sullivan and Tolbert have been quoted about misreads by WR's, I assume the problem is the inexperience at WR and not blake.
Teams are doing what they should, gang up on the run, force us to pass and then blitz. Until Blake has the confidence in his WR's to make the right adjustments, you're going to see some uncertainty. early in the year he made throws that got picked in part because of those reads, now when in doubt he's holding the ball.
So he may take some sacks that bother us but I'd rather have a sack than a pick and in case nobody's noticed he hasn't thrown one the last 3 games. If he comes back next year with this same group(and hopefully a new big play guy) I think you'll see a much more confident QB because he'll have more confidence in his WR's than he does now. Right now he's got the choice of making hot reads and throwing the ball trusting his WR will make the right read, or being careful, which is what he's doing.
