"Grandy is on the court he will, for the most part, draw their most physical defender. I think this could open up a lot of space for Loe who doesn't do well against athletic, physical defenders."
I'm affraid I disagree. If teams scout SLU, they will notice Glaze spends the majority of his time on the offensive end of the court setting screens. Literally a zero on the offensive threat levels. Gets his points by crashing the boards and, at least last night, overplaying the passing lanes and getting easy layups (Product of playing Dukes that won't happen again).
Basically, teams won't waste a key defender on Glaze.
BUT, he is another body off the bench that can provide energy and toughness when needed. Instead wanting him to have a 'big' role, be content with him perfecting 'his' role.
