08:22 AM ET 04.08 | Floyd Mayweather says the game is a pick 'em, and he'll wait a bit to put his money where his mouth is. The undefeated boxing champion, basketball fan and avid sports bettor will have an interested eye on the early action of Michigan-Louisville in the national championship game at the Georgia Dome on Monday night. "I'm going to watch the first half, then I'll bet. Probably $50K," Mayweather said Sunday at Ruth's Chris Steak House. "When Syracuse had a lead over Louisville (in the Big East tournament), they played comfortable in the second half, (Louisville) was able to come back. Same thing they did with Wichita State. But I think that if Michigan gets a lead like that, it's going to be kind of hard to come back."
