Celtics say goodbye while eyeing big return

Al Horford has officially signed a multi-year deal with the Warriors, ending his storied Celtics run and posting a heartfelt farewell. Meanwhile, Jayson Tatum is back on court just four months after Achilles surgery, stunning fans with his recovery.

Boston now heads into training camp with new majority owner Bill Chisholm, while Tatum’s workouts are so sharp they could probably break a backboard faster than your uncle breaks his New Year’s resolution.
