Manu has been a real piece of work from the finals on tbh..He really seems to not care all that much and if this his evaluation (which would explain him taking about as much money as you could expect) then how I feel about him is more than justified.
Let's hope his choking a** will be able to handle more than 20MPG, play a full season and actually produce for his money.
One subtle thing to look for, which I will preface is strictly speculation on my part, is the trust issue. For the first time ever, there is a risk of TP/TD/Pop not trusting Manu. I think they always did and really could live with him, but deep down they know what cost them the finals. After seeing that and how gutted Duncan was, I don't know if they will ever quite see Manu the same way. Especially if they here he honestly believes he played so-so.
I'm not saying they won't pass him the ball or even talk bad about him, but the thing that has always been there and allowed this team to win is that trust between Pop/TD/TP/Manu. Will be interesting to see if Pop starts yanking him out of most key moments, not going to him and if the Big 2 don't really see him as a big 3 member any more.
