From what I can tell Berrios has absolutely nothing to do with Treon Harris....
Berrios was not a high priority target for the Coaches since we have 3 big fish in SoFla we're trying to nab in Dixon, Lane, and Rudolph. Even JoJo. There just wouldn't have been room to take 2 of those (presumably Dixon and JoJo) and then also take Berrios.
When Kaaya called the coaches raving about Berrios after playing with/against him in the opening, the Coaches changed their mind and trusted Kaayas word for it and also saw his outstanding performance and the ridiculous numbers he put up.
I think its as simple as that. I don't think this had anything at all with Booker T Washington.
