Before I begin, let me just state that, if I get to vote for who should start at QB for Ohio State, I'd vote for Troy Smith.
But I'd like to at least give Zwick the respect he deserves by comparing how each quarterback did through the season. And I'm comparing the two quarterbacks based on the most important stat (or possibly ONLY stat) - wins and losses.
First, Zwick: He beat a couple chump teams - Cincinnati and Marshall. He didn't look great against Marshall, I'll agree. But the win is a win. (Ok - some of you will say Nugent beat Marshall. I agree, but Nugent didn't seem to want to be QB.) He beat a really tough NC State team. Again, he didn't look great, but he didn't lose the game. Finally, I thought he looked really good against Ok St. Possibly his best game as a buckeye. Sure, the defense should get the credit for winning these games, but Zwick (like Brent Musberger's least favorite player - Krenzel) didn't lose them.
Then he lost to NORTHWESTERN! SUCK!!!!!! That may have cancelled out all of his good games the rest of the season. However, if you consider the offense scored a bunch of points (I forget how many - maybe 30?), and it was the defense that lost that game, maybe we shouldn't be so hard on Zwick for that one. The one time the offense actually does something is the time the defense doesn't even show up. He also lost to Wisconsin and Iowa - both really good teams.
Zwick's record: 4-3. Against "good" teams: 2-2. Against "bad" teams: 2-1.
Smith: He started off with wins against Indiana and Penn State. Hoo-rah. I think the only team that couldn't beat Indiana is the team of Kerry/Edwards. Then he beat Michigan State. (I know.. HE didn't beat Michigan State, but I have to give him credit for beating Michigan State if I'm going to give Zwick credit for beating Marshall or NC State.) And I'm not sure if Michigan State was a "good" team or a "bad" team. I'll put them in the "good" category. Anyway, he lost to Purdue - a really good Purdue team, that should have beaten Wisconsin and Michigan.
Going into the Michigan game, Smith's record: 3-1. "Good" teams: 1-1. "Bad" teams: 2-0. I think that the two QBs are pretty close, as far as their records go.
BUT (here's where I put all my support behind Smith) Smith beat Michigan. He not only beat Michigan, he STOMPED them. And it wasn't like Michigan State, where Ginn bailed him out - Smith looked awesome. He scrambled well, he threw well, he threw while scrambling well.
The ONLY thing I can find against Smith is his off-field problems. "They" say that that's why Zwick started the season, and why Smith lost playing time. And, of course, he was benched for the Alamo Bowl. If he can get his act together, I think he'll be the only quarterback I can think of to beat Michigan three times. AWESOME!
