How do you like that Celtics and Hawks series?

personally i am shocked. I thought it was gonna be a blowout. I guess they are like the Mavericks. They have an awesome season then they get to the playoffs and buckle. I still think they will get farther than the mavericks last year but i'm starting to wonder if they will even get to the championships. The Mavericks had a problem with Golden State during the season so I wasn't horribly surprised but the Celtics should of had this series locked
