How many snaps did a QB with a name other than Vandenberg take last year? Nearly the same as the number of snaps taken by any QB with a name other than Rudock has taken so far this year. When one running back handles more than 54+ percent of the carries, another has about a sixth of them and a scrambling quarterback takes up another sixth or so, can you honestly claim the other RBs were "tossed into the mix"?
Yes, all the other RB's were tossed into the mix. Bullock, Canzeri and Daniels all carried the ball multiple times in the first half, when the game was still in doubt for meaningful time. So what if Weisman had 30 of the carries? He's been the most-effective RB so far, the others were also effective. That's how it's supposed to work.
What good does it do to talk about Vandenberg taking all the snaps last year? Is the opinion that Beathard is supposed to play just because? I'm all for playing multiple QB's if he and Rudock were close, or if Beathard brings a dramatically different skill set to the game than does Rudock.
But I'm not sure a person can say that Iowa isn't playing lots of guys (especially on offense). In two games, WR's to play extensively include Martin-Manley, Cotton, Shumpert, Hilyer, Vandeberg, Powell, T. Smith, McCarron (I might be forgetting someone). TE's to play are CJ Fed, Hamilton, Duzey, Kittle and Krieger-Coble. RB's are Weisman, Bullock, Canzeri, Daniels. The OL has played 6 guys a lot (Donnal plays about the same number of snaps as do Bofelli and Walsh. I would guess that the number of wideouts seeing extensive time might decrease as we get into the season and guys start outperforming other guys.
Iowa still has issues on offense (lack of speed and a play-caller who doesn't have a great feel) but it's not for lack of guys getting opportunities.
