Not shocked at all. I would be more shocked if he went through a season healthy. This years version of the Celtics is much, much, much more enjoyable minus Irving. No surprise that they are a much better team and everyone seems to be enjoying the game again. Tatum and Brown won't say it, and I don't expect them to, but they are clearly better off without Kyrie around. Kemba has been a godsend to this franchise.
I would expect Dinwiddie to bolt after this year. As he should because he is a starting PG in the NBA and should get paid. The other obvious reason is that he is going to be the back up to Kyrie. While that usually means you will get a ton of playing time because Irving is perpetually injured, it doesn't mean the Nets would be willing to pay him what he is probably worth on the open market. I would love to see Spencer end up in Boston. I am a fan of his.
