Receivers blocking is huge. I think they've improved as the year has gone on but there have been many times where a play was stopped for little to no gain because the receiver didn't hold his block.Maybe physically, but is he at all the type of blocker those two guys were? They were elite in that department. Maybe Higgins is, but I would guess not considering our run game overall is not as good as it was when we had Lazard and Butler blocking at the 2nd level.
Side note: I am pulling for Daniel Jackson to get more involved again. After his break out game vs Oklahoma State he has been pretty quiet.
