Out of all those schools you say are recruiting him, none have offered Zeller a scholarship. I saw Zeller play back in January, and I doubt he's improved that much in the last 3 1/2 months. He didn't even lead his Washington Hatchets high school team to the regional finals of class 3A in Indiana. If you're not familiar with Indiana high school basketball, you have to win sectionals, regionals, then semi-state to make it to state-- so Washington didn't even make it close to state.
I don't know why we're debating this, because Tennessee won't offer him... not unless Pearl gets really desparate, which I don't think he will with the talent in the class of 2008. Zeller would be a waste of a scholarship. He can't compete in the SEC, but I'd say he's a good mid-major prospect.
