If it seems like everytime that the Celtics have a chance to win it all, someone very major gets hurt, it's because it's 100% true. 2009 there was KG. Then in 2010, KG was still not back to 100% and Boston looked liked thye win regardless and then Perkins went down. Then in 2011 Rondo. 2012 Jeff Green out for the year. Then Rondo torn ACL in 2013.
Flash forward to when the Celtics got good again and Isaiah Thomas goes down with his hip issue, then Hayward and Kyrie, and aon and on it goes. Celtics could have won the Micky Mouse bubble title, but Hayward got hurt again and Kemba's knee.
