There was some talk of Mellusi & Allen being in the backfield together. We'll see. They both seem willing/capable of blocking for each other so it's a possibility.
Based on Saturdays' game, the D-line really misses Benton in the middle, and Isaiah Mullins. One isn't coming back. Hopefully Mullins will be soon.
I think they may have been effected defensively (not scheme, but aggressiveness) when that little wheel route or whatever it was went for the big gainer in the 1st half. I think there's sufficient ability to, with experience, press up a lot defensively. But there has to be a better pass rush to compliment that. that's where Peterson, Pietrowski, & Chaney come in as I think that mainly has to come from the LBs & maybe Mullins. Darian Varner & T J Bollers may help there but didn't really see the field Saturday.
Latu at S needs to play a lot better. Ashcraft looks like he totally belongs, one game into his career. That isn't easy for a TE.
There may/may not be one "go to" guy at WR, but the overall group is IMO fine.
I think Mordecai was a little over-anxious AFA going through progressions. Get more comfortable looking downfield & the shorter stuff will be much more effective.
