Mendenhall and BYU basketball coaches Dave Rose and Jeff Judkins will be able to provide the entire COA amount to their scholarship athletes because theirs are so-called "head-count sports." Other sports at BYU and elsewhere are referred to as "equivalency sports," meaning they have a certain number of scholarships that they have to divide up among their teams.
For instance, Littlewood has 11.7 scholarships (and 11.7 COA stipends) to distribute to his roughly 34 baseball players; Eyestone now has 12.6 full scholarships/COA stipends to disperse to his track team, and so on and so forth.
