Perhaps you know by now, the Celtics signed Horford. So Isaiah Thomas + Al Horford + Kevin Durant would certainly be a contender in the East and would match up very well than Cleveland. I'd even say that adding Durant would make Boston the team to beat in the East. :NasWinsAgain: LeBron & co. definitely wouldn't want those problems.
Then there's the fact that Boston would have enough assets and cap space for another player (maybe Jimmy Butler) even after the addition of Durant. :Plotting:
What a time to be alive if you're a Celtics fan.:GladBrad:
