Regarding open practice, walked into Ubben in early 2000's and saw a very raw Roger Powell working with Coach McClain. From what I saw and what he became even later his sophomore year is incredible. I also walked into Ubben the summer of 2004. Saw Brian Cook comeback to school the 2004 team, best player on the court. Remember the 7'4 footer Smith leaving the court upset, not sure why. Seemed frustrated with himself being handled by Cook.
Envious of those who can catch these practices, great to see the players/process outside of regular games.
