Much attention will be on Wildcat point guard Mike Bibby and his father, USC Coach Henry Bibby, but for the Trojans there are more pressing matters. Freshman guard Danny Walker will undergo surgery on his right knee Friday and probably is out for the season. There is the question of whether Rodrick Rhodes’ injured knee will hold up. And does Jaha Wilson want to play? He was suspended for the loss at Stanford because he walked out of a meeting. Henry Bibby denies Wilson has talked of quitting the team, but is Wilson ready to be the inside player USC needs? The Wildcats also have high-scoring forward Michael Dickerson (23.6 points a game) and guard Miles Simon.
