Hall will get minutes backing up the PG spot and Saunders will get a lot of the minutes that Knell would’ve gotten if he wasn’t injured. Robinson is a lock to be in the main rotation at the 2 and 3 sharing time with Spencer and Gideon.
It will be tough for any of the other newcomer underclassmen to get much time on the floor, especially the walk-on guys. Teams just don’t go much deeper than 9 or 10 guys generally, BYU’s top 10 (in no particular order) will likely be Fouss, AAA, Waterman, GG, SJ, Williams, Robinson, Saunders, Hall, with maybe either Stewart (PG3) or Toolson getting very minimal minutes.
Walk-on’s like Webb, Hayhurst, Dong and McGregor will get an occasional minute or two of garbage time in blowouts.
Christenson is a junior (not an underclassmen) so I didn’t list him here but if I did he would be in the last group getting garbage time
