Demin is the most talented and should have the most impact of the bunch (though I'm trying to keep my expectations reasonable considering he'll be a true Freshman). Mag and Keita as experienced big men should have a lot of impact as both will see significant minutes at the 4/5. Crawford is incredibly talented, but is most likely to end up buried on the depth chart with so many quality guards/wings on the team.

If you included Baker on the list, I would put him at #1 ahead of everybody.
