Well, since it's a sports blog we can use hindsight all day...in hindsight, Rozier for Kemba was a mistake.
It was a mistake of the majority of this blog as well, who somehow decided that Rozier sucks and is horrible and will always be crap. This despite what he was clearly capable of (see playoffs prior to Kyrie arrival).
As a Rozier fan, I nonetheless supported the trade for Kemba as it was such a refreshing change from Kyrie. Also, when a player I like is getting bashed to pieces on Celticsstrong sometimes that influences my opinon of trades...like...yes player I like go forth and prosper elsewhere. Anyway, Kemba was awesome prior to his knee woes.
So, instead of criticizing Ainge, who I hold in highest esteem, I'll just say hindsight has proven this deal wasn't the best for the C's.
However, things aren't done yet. Kemba could go off in the playoffs and this whole thing reverses course again.
(also, just want to add two reasons I like Rozier...physical profile, rebounds, and low turnover rate. I hate turnovers. I think being a low turnover player makes up a great deal for a few too many shots...I much prefer a missed shot to a turnover).
