This.No, because he was told it would happen and doesn't need to make any assumptions for a flimsy motivation on a stupid theory, schmuck. That's the difference between what Beamer knows with support and the assertions you pull out your ass.
Listen to the press conference. Beamer said he was called 10 minutes after the commitment and told Barnham would flip on Wednesday because "it was the plan all along." Additionally, Beamer said he was on the phone with Barnham and Barnham's mom at 10:33 last night and they were thanking Beamer for the opportunity they were giving Barnham. That's a lot more information than you would normally get during a press conference.
My inference from all of this was that this wasn't a kid that made a tough decision on Saturday and then tossed and turned all weekend and then made the best decision for him but rather something else (Leverage for NIL? -- talked about later by Beamer unrelated to Barnham). At first I actually felt sorry for Barnham.
