Incredible drafting by Ainge. It's very rare for a 19 year-old kid to be the best isolation scorer on one of the best teams in the NBA.
This is an odd statement by a guy who has been consistently anti-Irving, especially over the last few days. It seems like you are just trying to inflame another reaction on a different board. Irving is widely regarded as one of the best in the NBA at ISO play. He is certainly best on our team.
I like Tatum. You could argue that he is second on our team, but I don't think you could argue he is first.
As far as the argument for the second best on our team, he has had very few pure ISO plays this season. Most of his points are attacking closeouts on pick-and-rolls or kick-outs. Morris and Horford are probably better right now than Tatum, but Tatum has a much higher ceiling than both guys.
All of that being said, he is at least Otto Porter right now already, which is pretty awesome. Great drafting by Ainge. Sky is the limit in CBS system.
