Former Blue Devil Cooper Flagg had a tremendous rookie season last year, winning Rookie of the Year over former roommate and teammate Kon Knueppel.

What will he do for an encore? Well, it’s going to be interesting.

First, many fans think that he’s grown significantly. And at 19, that’s certainly possible. He entered the NBA at 6-9. If he’s now 6-10 or 6-11, with his mobility and skills, he’s that much more of a problem.

But that’s only part of the problem the rest of the NBA faces: according to his trainer, Matt MacKinzie, Flagg has put in the work to be significantly improved this season.

You can be sure he put a lot of time in the weight room as well. If he’s up to, say, 220, that would mean he’s gained 15 pounds. If he’s grown taller as well, he’s going to cause a lot of problems. And if he has improved his outside shooting, he’s going to be a nightmare.
