Duke associate head coach Chris Collins says he is interested in becoming Illinois' new head basketball coach.  The 37-year-old Collins has been an assistant at Duke under coach Mike Krzyzewski since 2000 and also played at Duke.  Collins, who is the son of Philadelphia 76ers coach Doug Collins, grew up in the Chicago area and starred at Glenbrook North High School.  On Wednesday, VCU head coach Shaka Smart turned down an offer to replace Bruce Weber as the Illini skipper.  Weber was fired on March 9th.
