here's my take. Baylor discovered Perea in Colombia. They recommended he attend high school in the states. They weren't "smart" enough to place him I guess. Indiana weaseled their way in there with Perea. They got someone close to this Adams guy on staff at Indiana to help IU have the inroads to Perea.
Who knows the full context of the text. But I'm guessing Morefield was upset that the rug was being pulled out from underneath him. It looks bad on the surface. But seems to me like Indiana orchestrated/set this up to try and eliminate Baylor from consideration. I'm sure the Indiana sources leaked this to the media. Looks genius on the surface- have to admit.
I don't know the answer to this perhaps someone does. If a kid from overseas comes to the states and has to have a legal guardian (in this case the AAU coach who wants to steer him to Indiana)... what happens when the kid turns 18? Doesn't his mom still have to sign the LOI?
