Imo, it all depends on
- Kyrie's trade value
- Danny's optimism regarding Kyrie's decision next summer
For instance, if I could flip Kyrie for let's say KAT, that's a trade I'd do regardless of what I expect to happen next summer.
Likewise, if I were sure Kyrie plans to leave Boston via free agency, I would probably be willing to trade him for a lesser player. Let's say in a 3-way with Portland and NY for McCollum.
With all that said, I fully expect Kyrie to stay with the C's for the foreseeable future. Personally speaking, I 'd trade Rozier at the deadline and then offer Kyrie a 5-year max (or close to max) next summer.
