Sorry but that's what happens when you're the only real threat. Arguably, the best player in the history of the NBA is on the Cavs. The second best player in this series is also on the Cavs along with the third best. Boston has the fourth best player, when has that ever been a reasonable matchup? You switch Lebron and IT and this is an exciting series but short of replacing IT with the greatest player ever, this is a huge mismatch and reveals nothing about IT IMO.
IT needs to have the ball to score, yes, but he doesn't have to pound it to death like a lot of players do. And he's a great decoy, you can't forget about him just because he's playing off the ball if you have other weapons. Boston has no other weapons. Seriously, who else scares you on that roster? Old man Horford? Marcus Smart? Tristan Thompson might even be better than any Celtic not named IT.
IT was overrated all season long, last year too. But he's a great 3rd fiddle despite his shortcomings. It's not his fault that Boston doesn't have anyone capable of taking that first or second spot.
