Maybe. But what can Reed do about it?
Assume for a moment that MP was a Cortese guy. Cortese then was basically fired because his vision did not square with the Board's vision. At that point, it becomes a huge uphill battle to sell MP on your vision. You know he pretty much disagrees.
There's no reason for MP though, to just go and start being a jerk. He knows he can force a move this summer, so why not at least hear Reed out and keep the options open. Unlikely he'll change your mind, but maybe he does. Besides, looking like a jerk doesn't exactly help his future employment prospects. And probably MP isn't really a jerk, he's just not really into Saints very much.
For Reed, there's no point in bullying MP since he holds a lot of the cards. If you're trying to convince someone, you have to be nice to them.
To the extent that either of them openly disagreed or butted heads at a meeting, there's no reason for either of them to reveal it publicly anyway. Since that only makes them both look bad.
So no, I don't think Reed was necessarily naive. It pretty much had to play out that way, with both sides going through the motions and listening politely to each other and not getting into a pissing contest especially not publicly and no one really changing the other side's mind.
