Durant- Linked to Warriors (who can pay the most), Knicks, Nets (With Kyrie). Torn Achilles adds risk.
Kawhi- Just won title with TOR, linked to LAC (home sweet home)
Butler- PHI rumored to be willing to go full five year max, rumored to want to play with Kyrie
Irving- He's gone
Horford- Linked to LAC (with Kawhi), Dallas (112 Million!?!)
Harris- Not worth a max, redundant with our wings.
Russel-Maybe if BRK renounces him, PHO, CHI, LAL all rumored
Vuc- Do we really want a 29 year old max center for four years? Nope. Just takes shots from the Jays. Overrated, had his best year in a contract year. Didn't show up in playoffs.
Kemba- Do we wnat a r year max small PG? That player type does not age well. Also, CHA can pay him about 60 something million more than BOS can.
In short, I'm not seeing a viable free agents option here.
