I watched 90% of last Saturday's game, but I don't recall seeing Bigelow get ANY carries from scrimmage. Or any screen passes.
I believe he was used exclusively as the kick returner. And he seemed remarkably tentative on kick returns. Showed no speed, and was easily tackled for the most part.
Did something happen with him that was not generally publicized? I hope he is still physically ok, and that worries about further injury are not holding him back. (Easy for me to say, harder for him to do, I realize.)
Assuming Bigelow's ready to go, I think JT must USE him.
