Lots of teams could beat UK on a given night, even some SEC teams came close. But you have to like our odds against anyone.
If you want to be afraid look for the matchups that have beat Cal's teams in tourney's passed. Teams with ultra quick guards and serviceable bigs (athletic) that can break down our defense. Teams that drag the bigs out can make it a closer game, but as we saw against GA this team will figure that out. Teams that zone can slow down the offense, but this team won't settle for jumpers all night and will break through the zone.
The only real fear is a team that score on our defense. To that you have to have guards break down the perimeter defense like Kimba Walker and that other UConn guard.
