Combes ran behind a new fullback and five new offensive lineman and a new tight end. None of them started the prior year. So who made who better? Did Combes make Glenn's line look good, or did Glenn's line make Combes look good? So I would answer your question...yes, all of those guys would have rushed for more yards. All of them are seniors with at least two year's varsity running back experience that are talented enough to create plays on their own. I thought Jones improved as the season went on...definately once they started to utilize him more as their feature back. He needed help opening holes though. Combes, Olsen, Weller, Hansel, Scheiber...those guys can create plays when nothing exists.
As far as any snub on all-conference, those coaches want the best players to represent the conference. Some years there is a lot of depth...other years not. I'd say this year there was definately a lot of talent in the skilled QB/RB positions, Offensive Line, and Linebacker positions. It just so happens that is also the positions where the players Triton put up played.
