I picked the Cavs in 6 as I believe Indiana will give Cleveland a run for their money; also, depending on if Garland comes back, I wouldn't be surprised if this series goes 7.
With Garland, the Cavaliers are stronger, but without him, things get a little shaky; I do believe they'll overcome the Pacers, but it won't be an easy sweep like it was against Miami.
Indiana actually has a very good team behind them compared to the Heat. This series will be a dogfight, but in the end, Cleveland should prevail.
