That smile on Horford's face says a million words about Boston's fan base. Al spent years carrying Atlanta in games far more important than a first-round game 7 for a franchise with 17 titles, but he literally cannot contain his smile because of how rambunctious and appreciative the crowd is. THIS is the reason he and other free agents want to come to Boston. Yes, Ainge and Steveens are amazing at their jobs. Yes, the Celtics role players are Patriots-esque. But the reason players want to come to Boston is we, the fans.
