I haven't seen any practices but agree with you that Edogi should be a defensive force inside. Haith says we will be stronger inside with Edogi, Igbanu, Etou and Magnay.
Birt did defend well once he became a starter. It's always tough for frosh to come in as good defenders. Juco's are hit and miss depending on the program they played in. However, I do think Wheeler and Henderson will be solid defenders, due to their experience and athleticism.
Artison can be a solid defender, with his length. I expect to see him block or alter a number of shots. Magnay, although a frosh, comes in with good credentials as a defensive player.
I do think we have the size and athleticism to be a good defensive team. However, with so many young and inexperienced players to the speed of Division 1 basketball, it will take some time for us to gain team chemistry and to learn each teammates tendencies. I think by the midway point of our schedule, we could be a good defensive team.
It will help that Etou and Henderson have D1 experience and Artison went up against D1 talent at Fresno and in the Seattle area league where he participated against college and pro players.
