I think D forgot about his film from last year and instead, put too much weight on what the staff told him and what he supposedly saw on greentree. The injury excuse is just that - an excuse. He is what he is - an undersized kid being asked to do things he shouldn't be doing and a kid who is a marginal athlete at TE. JMO.
Yeah, you pretty much have it. I don't think this OL is as bad at the run as the stats indicate. There are a few issues with our run game - no vertical threat of Arroyo, a dynamic QB and unpredictability in the run game.\
I think this year's WRs are just as good as last year's. Martinez was a nice RB but not as dynamic as you indicate. I think we are fine at RB as well. So what's different? QB and TE. There's your difference. We had difference makers at both. Compounding the issue is our tendency to be VERY predictable on offense. Those things amount to a stifled run game.
