The Celtics have enjoyed four straight winning seasons, with the trend likely continuing this season despite losing several key pieces. Kyrie Irving, Al Horford, Terry Rozier, and Marcus Morris all bolted for greener pastures. These may seem like a devastating losses, but opportunities are now present for young guns Jaylen Brown and Jayson Tatum to step up and take their games to the next level. Gordon Hayward is another year removed from his gruesome injury and should be a bounce back candidate. Oh, and the additions of Kemba Walker and Enes Kanter don’t hurt either. The Celts did some addition by subtraction, and are primed to challenge for the Eastern Conference title yet again.
