Agree with the comments about PGs and athletic wings. If they can hit the pullup midrange shot too, they are deadly. But everyone is neglecting the bigs, so a quick shout out to:
Amir Johnson - Always hurts me when I'm playing the Raptors. Athletic, fights inside, but also knocks down shots when I get sucked in on the drives of DeRozan, Lowry and Ross.
Julius Randle - I don't know why, but I really struggle against him. Athletic and a good scorer, and a threat to get 20-10 every time I play him.
Bismack Biyombo - Not a scoring threat, but I just hate playing against him. The best post defender / rebounder in the game with a low overall rating.
Joseph Nurkic - Absolute beast inside. I traded him in my MyLeague in a package for Rudy Gobert... first game back he destroys Gobert for something like 35 points and 15 rebounds
