Knicks vs 76ers has got to be the most interesting series of the first round if you ask me, so many swings, spins, twirls, twists and turns, you name it, there is nothing this series didn't offer, I also yearned for a game 7, but that probably would be unfair to NY Knicks they were the better team and duly deserve their spot in Eastern Conference semi-finals.
That's already 2 possible game 7 that have ended with the Indiana Pacers also getting past the Bucks, I really don't see the Cavaliers or the Mavericks series extending to a possible decider in game 7 with the way things have turned out today

Yeah, i'd say it's up there with the Mavs/Clippers series. The Pacers/Bucks series should've ended within five, but the Pacers couldn't keep up with how the Bucks were shooting the ball well during that game five.
The Magic/Cavs series can easily go the distance since the Cavs never kept their road games close in Orlando, and the last two were like 20+ point wins for the Magic.
But this is in region of you never know right?
That's true, all it takes is for a team to have a shooting regression, and we could have two series going to a game seven.
