Outside of injury-related recovery/working his way back to form, there is no freaking way Hayward is coming off the bench. The Celtics just shelled out a max deal for this guy to be a #1/2 option for the team. Maybe if he blows it after a quarter of the season, but out the gate there is no way he is on the bench.
Baynes will only be here if Baynes wants to be here....meaning he is going to have to take leas money. There will be a very specific role for him as a key cog in the big rotation and a spot-starter for occasions where we play the few bigger frontcourt teams left (New Orleans, Detroit, Philly)....but he’s realistically the 8th or 9th best player when the current roster (with Kyrie and Hayward back healthy) is intact.
He can definitely start for a crappy team and get more money if he wants to. So that’s basically up to him and his agent to decide. He seems very happy here, so we’ll see.
The starting 5 next year is obvious
Kyrie/Brown/Hayward/Tatum/Horford
Hayward and Tatum will be an innerchangeable wing duo. I see Tatum as the KD type of wing on the offensive end, wirh Hayward being more of an outside-inside wing as the better perimeter shooter (by a small margin). On defense it will be a challenge, but as Tatum bulks up, he should be able to hang with most PF’s.
Rozier is the obvious 6th man, with Smart/Baynes taking turns as the 2nd and 3rd sub depending on matchups. And don’t sleep on Thiess! This is gunna be such a fun team to watch next year, assuming every current player remains. Or Danny takes another swing for the fences.
