Well the way I see it, he's 6'3" and 296. Pretty much the same as the current centres we have. Barnes is 6'4" 306 and Rhaney is 6'2" and 301. Stash Dismukes on the PS, let him bulk up and see what happens. If nothing, no big deal it's only the practice squad. I feel he'd be a better project then a guy like Laskey on the PS. But, I didn't watch any of his preseason games to know how he's done so far.
I think we want to develop Laskey as an actual full time FB. Harkey is nice, but having a true FB would be imperative if we're true to our commitment of being a ground and pound team. IMO, I'd either replace Hagen, Worthington or Longarce. Though Laskey was fairly underwhelming, I think he might be able to improve.
But I don't think the guy has any bulking up left in him, I believe his frame is maxed out. He didn't really bulk up even through college, gaining only 24 pounds from the beginning of college to the combine, also that won't change his hand size or his arm length which is part of his problems in the first place.
I wouldn't mind taking a flyer on him, see what we can get, no real risk involved, but I don't think Dismukes has it.
