Hate to say this but it reminds me of the Celtics series from the late 2000s.... This Bulls team isn't anywhere near that good, but Cavs in their injury-depleted state are just a little overmatched, and Lebron 2015 isn't Lebron 2009, plus his jumper is messed up.
I wouldn't be surprised to see the Cavs come back in the 4th and have a chance to win since the Bulls are inconsistent too, but it looks like the same old story of previous games... they don't have the consistency needed to beat Chicago. Cavs are superior with both teams at full strength, but with the current team I think it's Bulls in 6.
