I don't really understand the whole "manipulation" argument. Kirk and his agent were good negotiators, and if they outdid the UI in the negotiations, that's not a manipulation, that's just being better at it. Manipulation connotes he did some underhanded, unethical or even illegal, there's no evidence of that, unless you want to argue that Kirk's style of football put Barta and the rest of the gang at the UI into a trance such that Kirk was able to get whatever he wanted. If in 5 years or so Kirk snaps his fingers and Barta shakes his head and wonders where's he's been for the past 15 years, then I'll join the "manipulation" chorus.
