The thread title should read, "What is Al Horford going to do with us?" because this is all really his decision. I am not sure how close he was to Kyrie, but watching him walk in FA and missing out on AD probably has him questioning the future of this team.
It would be very much appreciated if he would let us trade him to the destination of his choosing. Luckily he doesn't seem like the type to be swayed by the glamour markets that all have cap space right now. Of course I would love him back, but he would have to be playing for the love of the city over winning a championship at this point...and that doesn't seem reasonable given the media and unappreciative fans in Boston.
