On First Take, Max Kellerman thinks Hayward to Boston would be the ABSOLUTE BEST fit for both sides, and could legitimately contend against Cleveland.
Take that as you may.
To me, the issue is, as another thread on here states, if we add Hayward, what other big or PF are we adding? Because then we'd lack depth there with so many departures.
Horford, Zizic, then who? We also lose MLE signing Hayward, so that's not an option either (though that would have been nice for someone like Gibson).
