I voted no. If he comes here, he'll make some playoff runs while the only true big on our roster ages out sooner rather than later (i.e., Horford). Then, he'll find himself surrounded by talent competing for his spot in the rotation (i.e., Tatum and Brown). I don't see how he can be convinced that coming to Boston is a good idea with the core we've assembled and the "assets" we've accrued. At this point, it's almost better to let Hayward walk and accept our fate as a middle of the road playoff team with a couple of young prospects.
I will admit to being slightly more pessimistic than usual, but I'm quite convinced that we're done this offseason.
