Too early for this kind of convo IMO.
Guys still have a lot to prove, remain healthy, we don't know what will come out of the LaKings pick that has significant salary if conveys and could substitute them (eg. Baynes-Ayton/Bamba), the whole Hayward situation, who will kick us out of the playoffs and why.
Hey, maybe one of them is found with 4 pounds of weed in the trunk by then.
Baynes and Smart (to a lesser extent) are not cerebral players that can't be substituted in any way. I like both a lot, but it is too early.
Reminder: Last year we also had "players that must return", only 4/15 made it
