No, you cannot do that. The ext can only be signed with Indy. Now he can sign that extension and then in the middle of the year which under contract be traded but you can't do a SnT for with that ext as it only can't be signed with Indy for Indy.
Boston can ONLY sign PG to a three year ext for 8% raise no matter what. Now in the off-season, he can do 5 years for 10% raise each year due to his Bird rights.
How are you not getting what I'm saying? No where have I mentioned a S&T, I've said the Pacers would sign him then trade him, I never specified when. I know the only team that can give him the supermax is Indy, which is why I've said it several times, I know exactly how the rules work, and you keep saying the same thing again and again when I have made my point clear.
