White's main weakness is he doesn't run the ball at that effectively. Is he Lewis? No, He's not Faulk, Woodhead, or Vereen either. I'm sure part of the reason Bedard thinks White is a liability is a couple of times he missed a block and Brady got pressured and hit. I'm still waiting for Foster to get a shot, and now that Gaffney is back in the fold some people will want to see what he could do as well. I guess I'm not really sure what Bedard expects or who he thinks they could get at a reasonable cost. Also not sure why Bedard thinks Foster is positively, absolutely not an option.
Bedard even mentioned what I did earlier. They only need someone to find a hole in the defense and run upfield (and into the end zone if close enough). In White's case, he is the beneficiary of other targets drawing the coverage and he seemingly is the leftover guy that's open. In Lewis' case, Lewis is more often the intended target as a mismatch, which is 180 degrees the opposite of White.
