I wasn't able to watch the New Orleans game due to the Fox vs. DISH dispute.
So, the consensus is that Posey, in combination with Collison, stood up to O'Brien and helped get things changed at the end of the game? Please tell me that is actually so!!!!
If that is so, Posey just became the second most valuable veteran presence on the entire team, especially if he brings savvy and sanity to the management of games, especially during end of game situations. That would be a change in dynamics that could potentially alter the outcome of games that the Pacers would ordinarily lose due to mismanagement and lack of recognition of game flow that has plagued the franchise throughout O'Brien's time here.
I could quickly learn to like Posey if this is part of his repertoire!
And, if a side effect of this is that Collison is listened to more than a second year player normally would be due to having been Posey's teammate last year, that would help as well, assuming Collison doesn't actually want to play the game the way O'Brien has designed it offensively, giving some additional hope to better offensive execution from the pg position than we have seen in the past.
