Two big problems on offense: 3rd downs & red zone

[takethecake]

I think that the root of the problem is the offensive line. The right side of the line has struggled to open up holes in the running game, and therefore, our running game has suffered. Clinton portis and torain should be sufficient RBs behind a good offensive line, but trent williams and lichtensteiger have been our only really good run blockers so far this year. Our lack of running game makes us predictable, especially in the red zone, and thus we become easy to defend against.

I like seeing sellers involved; he's a freak athlete and is very versatile, although I cringe when he gets the ball because I'm afraid he'll fumble it lol. His run blocking has been very hit or miss this season - does anyone know what the implications of a zone blocking scheme are for a fullback? And I hope portis can teach torain and keiland or whatever rookie RB we end up with how to pass protect..
