In the summer of 2020, it seemed likely that Gordon Hayward was going to be signed-and-traded to Indiana. The offer was reportedly Myles Turner + rotation player + 2021 1st rounder.
Imagine how that trade would have changed our team? And Indy's?
Our 2021 roster would have been:
Timelord
Turner
Tatum
Brown
Smart / Kemba
With Nesmith, Pritchard, Grant Williams off the bench. No idea if we still make the move for Kornet, but there's a probability there.
Then, the following summer, we have Indy's pick (it ended up #13) and our own (#16). Do we still trade ours for Horford, or do we pick our reported target with either ours or Indy's pick? Or do we combine Kemba and a 1st for a different player?
Let's say we keep both picks, and hold onto Kemba as an expiring contract. Could we have traded #13 and #16 to move up to take Franz Wagner? Probably not, since at least one of those picks would probably have ended up lower in the draft. But, let's say the Pacers only marginally improve, and end up around 15th or 16th. We take Sengun and let's say Jalen Johnson.
2021 roster:
Sengun / Timelord
Turner
Tatum
Brown
Smart / Kemba
We still have the pieces to make the White, Brogdon and Jrue trades. We probably don't make the KP trade.
Our contending core:
Sengun
Turner
Tatum / Johnson
Brown / White
Jrue / Pritchard
That said, we probably would have still dealt Marcus, since he would be a bit redundant here. Who knows what we get, but he basically landed KP, a late 1st, and last year's 14th pick.
Obviously, there are hundreds of directions and changes that can't be predicted, but I've always been a sucker for "what might have been". The only sad part: no Horford to enjoy a potential championship (or more) with.
