A 6-foot-8 former Seton Hall hoops star is expected to get three years in prison after admitting he robbed a house near the South Orange, NJ, campus.

Kelly Whitney, 28, of Chicago, pleaded guilty yesterday to burglary, conspiracy and criminal-restraint charges.

He and ex-teammate Robert Mitchell held up several fellow students in an off-campus apartment in March 2010.

Mitchell pleaded guilty and testified against Whitney, who scored 1,448 points for the university from 2002 to 2006.
