Tonight at 10:17 p.m. ET the No. 2 Arizona Wildcats will take on the No. 6 Xavier Musketeers in a Sweet 16 clash on TBS which can be live streamed free by clicking this link. Arizona fans can tune in to the radio broadcast on 1290 AM The Source, while Xavier fans can listen to the action on 700 WLW.

Tonight's coaches, Sean Miller at Arizona and Chris Mack at Xavier, used to have a master and apprentice relationship when Miller ran the show at Xavier. Now, Miller is the solemn leader at Arizona while Mack has taken his place with the Musketeers. Arizona is the big program and the big favorite, and Mack's jovial nature reflects the situation.

"I don't know if Sean has a funny side," Mack said. "No, he does. I could share a few stories that may either get him embarrassed, maybe even arrested, but I won't do that. I'm kidding about the arrested part. He's got a dry sense of humor. He is a funny guy behind closed doors, but not very often. Not very often. He's ultra-serious. Too serious. He needs to loosen up."

He's leading a group of young upstarts at Xavier against a veteran Wildcats team that has NBA-ready talent on it. Xavier guard Remy Abell is pleased that most are taking the Musketeers lightly and said they don't need any outside observers to give them a shot.

"As long as everybody believes in each other, that's the main thing. We've got to believe. If you ain't going to believe, then why play? People are probably going to underestimate us, but like I said, we have to believe."

Vegas sure doesn't. The Wildcats are 10.5-point favorites to move on to the Elite 8, but if Xavier does pull off a big upset, they'll certainly be wearing Cinderella's glass slipper moving forward.
