Pitino could have similar results Lavin had his first year when he took over a senior laden team.As for everyone thinking there will be a wholesale change in SJU's roster like two years ago- I don't necessarily see that happening.
I think Pitino sees an immediate opportunity next year in an underachieving team with three all-conference players in Posh, Joel and AJ plus other valuable pieces like a 4th-year player in Dylan, a promising guard in Kolby, etc.
I'm sure he's thinking to himself that he could easily take an 18-win team and make them a 25-win team without jettisoning the whole roster. He has certainly walked into far worse situations before.
