The Hayward part is a young player that says he gets it, but doesn't really get it. The Irving part is far more interesting and if true, I have to really question not trading Irving at the deadline last year. The team was a mess and it seems like Irving was the major reason why. He should have been moved.
The Celtics were trying to win a title last season, and based on how they played against top competition during the regular season, there was every reason to believe that they had a shot based on talent alone. That's why Ainge didn't trade Irving.
Hindsight is 20/20, not to mention that the return for Irving would have been incredibly underwhelming anyway.
What talent? I mean that seriously. Boston had no true top end talent and that almost always wins the day in the post season. And for me it wasn't hindsight, as I absolutely said that thing all over this board (with much disdain from the masses) and also said that Boston should look to move Irving last year at the deadline as I had several long term concerns with even re-signing Irving let alone the chance that he would leave. In fact, I would have moved Irving and then used the assets to go hard after Davis. For example, I proposed some variation of this 3-team trade on this board a lot leading into the deadline last year.
Boston - Davis, Moore
New York - Irving
New Orleans - Brown, Yabu, Kanter, Knox, Ntkilina, Bos 1st, NY top 5 protected 1st
Maybe it wouldn't have happened, but it was a trade that seemed fairly reasonable at the time.
The simple reality is, Irving was a disaster from almost the minute he as acquired. He was a cancer wrecking havoc in the locker-room, just like he did in Cleveland (this board wanted to put that on Lebron, but it was almost all on Irving). And he is a player that gets love like, and firmly believes that he is a franchise player and superstar. He isn't and never has been. He has always been a problem and the team should have cut its losses and moved on, especially when Ainge failed to surround Irving with a true #1 (like say Kawhi).
