I have thought all along Keita will start with his better length and rim running ability, but maybe it will be hard to keep Fouss out of that starting spot with how productive he is. Despite what seemed like struggles at times in conference, Fouss scored the most pts/40 at 25.8, had the highest rebound rate, was the most efficient shooter by far with a true shot % of 64.9% (next closest was Richie at 59%), and was the best defending big. His player efficiency rating was 32.4 in conference, with Richie being the second best at 20.8 - crazy. Good argument to say he was BYU's best player last year, easily the most efficient.
Looking at all-time BYU stats for career, Fouss ranks top 10 all-time in the following. His efficiency and defensive contribution is very impressive. Fouss is really good, despite his height limitations (Does help to be strong as a tank and have really long arms):
Block Percentage: 4.5 (8th)
Blocks Per Game: 0.9 (9th)
Box Plus Minus 8.0 (1st)
Defensive Box Plus Minus 2.7 (7th)

Hope he can stay healthy and have a big senior season.
