The best quarter-final game in terms of match-up and intrigue is also the first (good job, Pac-10 schedulers).  Two teams that expect to be playing deep into March each year will now need to win the entire tournament to do so.  Can Ben Howland orchestrate a stunning turnaround?  Can Derrick Williams lead Arizona to their 26th straight NCAA tournament appearance?  It starts today.

What to watch:  Two members of the Pac-10 All-Freshman team go at it down low when Reeves Nelson and Derrick Williams tangle.  Nelson is returning from an eye injury and how he fares against Williams will probably decide the outcome of this game.  This also may be your last chance to see Nic Wise, Nikola Dragovic and Michael Roll play Pac-10 basketball.  I'll let you decide if that makes you happy or sad.
