I agree that Amar could be a good contributor. Heck, he's contributing already.
But you guys sound like Kobe deriding American basketball and focusing on how skill development is so much better in Europe. There's a grain of truth to that, but it's also vastly overstated.
Europeans are rarely exposed to physical play or the level of competition you see at even the average high school level here.
Ball movement and shooting look pretty until you face an athletic defense that bumps you and pushes you off the position you want.
Alibegovic plays like a bouncer at a bar right now. If anything, he needs to ease up on his physicality. You can can call his fouls from sitting in the upper level of MSG.
