There are lots of teams that whiffed on Jack Kelly including BYU. Kelly(91), Lassiter(86) and Bagnah(86) all had much higher 247 transfer ratings at the time BYU got them
Our 3 best players(Chase, Kelly and Batty) all had a lot of options at the time they signed with BYU so weren't necessarily whiffs by anybody when they signed with BYU
