According to Drew Deener, who does TV play-by-play for the Cards, Stephan Van Treese will be staying at UofL and not transferring. If this is true, it will give the Cards even more depth in the front court, as Van Treese can play both the Power Forward and Center positions.
As it stands, the backups at those spots are Zach Price, an inexperienced Sophomore, and Montrezl Harrell, a true Freshman. So it definitely will not hurt to have a veteran like Van Treese in the mix. He always plays with a lot of heart and will help out when he is called upon.
With the (likely) return of Van Treese, the Cards front court will look like this:
Gorgui Dieng 6’11
Zach Price 6’10
Stephan Van Treese 6’8
Montrezl Harrell 6’8
Chane Behannan 6’6
