This is a stupid ass topic. The Cavs have a great perimeter defender in Lebron, a good one in Waiters, and decent rim protection in Varejo. They also got a veteran defender in Marion that can come off the bench and also guard pretty much any good to elite wing in the NBA.
They're probably gonna be average defensively but they're gonna to have the most explosive offense in the damn league. You got 3 ELITE offensive talents in Lebron, Kyrie, and Love.
Lebron is pretty much an elite PG and big man in one while requiring the best individual defender the team has. He can play off the ball because he's a good shooter, he's an elite cutter and slasher, and he's Lebron James.
Love is a defensive nightmare because he's an elite offensive PF who can stretch the floor if you put a rim protecting big man on him or bully weaker PFs. Simply due to his rebounding ability and scoring, he causes a shift in defensive focus because he's so damn strong and smart about positioning that he draws defenders into him.
And then you got Kyrie who will now get to feast on less defensive attention plus Waiters who gets to defend on even LESS defensive attention.
They'll give up a 100 and score 120 plus they have two guys who can pretty much "turn it on" if they need key defensive stops.
