Louisville is set to open spring practice Wednesday with a few position changes.
Strongside linebacker Preston Brown is set to move to middle linebacker, where the departing Dexter Heyman leaves big shoes to fill. Brown had a breakout season in his first year as a starter in 2011, tying for second on the team with 84 tackles. Heyman led the team with 90 tackles, 16 tackles for loss and three interceptions, and started in the middle the past two seasons.
Deionterez Mount is penciled in at Brown's strongside spot. Incoming true freshmen Keith Brown and James Burgess -- in for spring practice -- will start off at the weakside linebacker position, behind Daniel Brown.
Developing depth at linebacker and finding a solid player in the middle, are two of the biggest spring priorities for the Cardinals, who are expected to be one of the top contenders in the Big East in 2012.
