Tiller managed the game well against NU, no doubt. Wasn't asked to do much and what he was asked to do, he did well.
Against A&M, it sounded like he did some good things, just made a couple mistakes that hurt us as well. As noted, both QBs need to play mistake free football for ISU to win. It's a bit of a different game if Tiller doesn't toss a couple picks. I don't think we win, but we're not playing so far behind and perhaps we can run ARob more.
Keep in mind that A&M defense is rather poor and we were relatively ineffective against them. Sounds like the makeshift offensive line wasn't a problem and our running back was healthy. Again, Tiller has done ok considering circumstances, but we needed much better play at the QB position to hang with A&M - we didn't get it.
Will see how effective Arnaud can be this weekend. OSU is good, they've also shown the ability to give up plenty of points and big plays defensively.
