These HS coaches are often father figures. It may be nefarious (he’s an OU fan, or wants to build a connection/network with the OU coaching staff), or he may think attending Oklahoma’s in the kid’s best overall interest for a whole bunch of reasons/Abiara may be leaning on him for the advice.
ETA: And after a few seconds of research, it appears his head coach is in fact an OU alum. Yeah, that’s pretty messed up of him if he’s the reason for the flip.
Let’s see if he’s on staff at OU in the next few years. *
