That's it? Pacers will actually make that move? Idk why they would.
I'm sure they'd want back picks and other young assets.
Would need to be a 3-team deal IMO. Scary thought if the Cavs could pull this off though.. 
Think a 3-team trade a more likely scenario than a Love-George swap. Pacers will need to rebuild if they lose PG and that seems a foregone conclusion. Love doesn't help that. They can't be too picky, but Pacers have the leverage of waiting until the trading deadline. We could be that 3rd team in theory given our asset stockpile and I would think Love would find such a deal acceptable.
Love to Boston
George to cle
Zeller, ,AB, Crowder, picks(hopefully not brk)
I don't think we would have the cap space for Hayward though, if we do this.
Can't they make the trade after signing Hayward?
They can, but it would be kind of awk to see the Cavaliers and Celtics, in a sense, helping each other LOL (in the middle of the season).
Like Cavs give their third wheel to the Celtics, while Celtics likewise allow the Cavaliers to get Paul George.
If they both are 1-2 again in the East... it would be a little weird if they made that trade.
