6 p.m. ET: No. 5 Ohio State at No. 10 Florida (ESPN/ESPN3) -- With the possible exception of Virginia Tech-Kansas State, this, my friends, is the game of your marathon. Florida, the media's preseason pick to win the SEC, is back in the national conversation after Billy Donovan's three-year rebuild thanks to the return of all five starters from last season's NCAA tournament team and the arrival of top-15 recruit Patric Young. Ohio State returns every non-Evan Turner starter from last season's 2-seed and welcomes the No. 2 class in the country to Columbus. That class includes forward Jared Sullinger, who, if he lives up to his considerable hype, could lead a deeper and more balanced Buckeyes team even further in the tournament than last season's somewhat disappointing Sweet 16 finish. How Sullinger and fellow freshmen Deshaun Thomas (the No. 3-ranked small forward in the incoming class) and Aaron Craft (who's been drawing big praise for his capable point guard play thus far) augment the Bucks' talented returners will be the key to Ohio State's season. We'll get a taste of that dynamic Tuesday night, but more than anything, this is just a great early-season nonconference game, almost as good as they get. I can't wait.
8 p.m. ET: No. 18 Butler at Louisville (ESPN/ESPN3) -- Louisville isn't as talented as in recent seasons, and Cardinals fans are probably bound to face their fair share of frustrations in what is essentially a holdover season until 2011's stellar recruiting class arrives. But this is a tough first matchup for another very good Butler team. Rick Pitino's young and inexperienced squad can be counted on to do two things, according to Pitino: Push the pace relentlessly on offense and pressure the ball relentlessly on defense. Butler has the benefit of some very capable guards -- Shelvin Mack and Ronald Nored; perhaps you heard about them during the Bulldogs' fairy-tale NCAA tournament run in March -- but a well-run Pitino press presents issues no matter your talent level or experience. Add in a tough road environment in the sparkling new KFC Yum! Center, where U of L fans will be experiencing the new building for the first time, and the result is a scary early road game that Butler will have to fight very hard to survive.
