I just don't see why we would trade Rozier.
Because there is a strong possibility that if we don't trade Rozier we'll eventually lose him for nothing to free agency.
Rozier is not going to be content to continue being a backup when he's demonstrated he's at the very least an above average starter.
Now maybe it is worth it to keep him for the next year or two, depending on how his RFA market plays out and whether or not he think the C's will match any offer and this force Rozier to take the QO. Having Rozier as our backup PG would obviously be a huge bonus for a championship run, but is an extreme luxury at this point though, especially if Smart is retained this summer.
I'd argue it's better to try to flip him for a young big man with upside to eventually take over for Horford.
We lose very important depth if we trade him and I guarantee it will bite us at some point next year, likely in the playoffs. You need a 4 guard rotation to compete, trade Rozier and you have a very important spot to fill with no money.
We talk endlessly about windows and going all in etc.. This is a time to go all in and risk one
player leaving in a year. Big deal.. And who the heck knows, maybe he'll end up playing his way into staying long term and we move someone else to make room. You lose all those possibilities the moment you trade him... for a rookie scale guy? A future pick? Ain't happening.
