Not going to rehash the Kyrie Trade. It happened in the Lebron 2 era. Hindsight is 2020, but personally I think we did OK, and more importantly we fixed a lot with the second trade that dealt IT.
As for summer league gems. We are not playing draft picks because they are on the team either way. No good or bad news can be developed from SL, that we have not already gained (such as Windler) The remaining PT in SL can be used to evaluate as many players as possible in the crucible, so we can see if there is anyone worth picking up. Personally I think there have been better performers than Wade, but I am a hack, so I will defer to the pros. I also thought Phil Booth was pretty good, though we have a ton of guards already, and I was pleasantly surprised by Bolden.
Blossinggame was a find last year. I saw him live in a couple of games and it struck me that he seemed to know where to go/be on both sides of the floor. While he is not star material, I think he is on that cusp of being an NBA backup,and to that end could be tradeable for another asset. So I am OK with his 2way.
