Training camp has started for the Dallas Mavericks and Cooper Flagg is delivering on expectations. If you haven’t seen the first video, you’ll like all this.

And you’ll like what vets Klay Thompson and Anthony Davis had to say about their new teammate too.

Davis: “Man, he has a lot of talent on both ends of the floor, but defensively, he’s going to shine. We’re going to put him in situations where you have to guard maybe the best wing, to have to guard Kevin Durant or Jimmy Butler or these guys.

“We have enough confidence in him to go out, send him out there and be able to guard those guys.”

That’s hugely impressive that he’d say that about a rookie.

And here’s what Thompson said about Flagg: “I’m most impressed he did not sit out one drill. I don’t care how many shots he misses, how many mistakes he makes. The fact that he’s in there and he’s competing every single drill, that’s what impresses me.”

Duke fans know what we saw last season. The NBA is about to find out.
