Rollie is more often correct than wrong. He has a leg up on most of us because he played with Rollie Massimino.
Marcus Smart is incredible on defense. It's just not as glamorous as the things players do on offense.
I recall one of those Miami teams maybe around the time we first got KG/Ray. They didn't have a dominating center either but showed what feisty team defense can accomplish.
I think in football there was a Baltimore Ravens team that won it all. They were putrid on offense, but it didn't matter. They only had to score a certain amount.
That is our team if we can add a younger version of an Amir Johnson. We are stacked at the 1, 2, 3 on defense as someone above said. It makes me think of that Miami Heat team. I remember that specifically. I thought, wow, they have no center, yet it doesn't seem to matter. Then on offense, Wade was in his prime.
Crowder is on his way to being a two-way player and I have confidence Marcus Smart is on the same trajectory. He's young and Rollie is correct injuries skew stats.
It's a team game with half of it played on defense. Smart is the team's best player with the most potential. He should not be traded under any circumstances unless it is an Al Jefferson for KG type of trade.
