Couple things on Jefferson-
He didn't play the last month of the season after having knee surgery - I would think that could impact his offseason as well, hopefully he's ready for fall.
Something I find fascinating - before his injury he had 4 games with a double-double. All 4 were wins, and 3 of them were the biggest wins for St Mary's - @ Colo St, @ San Franscisco and @Gonzaga. And in those 4 games he went 10-16 from 3pt range. The other 22 games he went 6-44 from 3! He started the season really cold from deep, going 2-26 in their first 9 games.
But his tendency to have big performances in their big games is a good sign - and the tie between rebounding and shooting well is fascinating
