Last year, the opponent's defense was focused on Henry at all times. Haanif didn't face defenses shaded toward him. This year, he is near the top of the scouting report. They are sitting on his left hand. They are collapsing hard when he starts his drive knowing that (A) he is going to the rim, (B) he does not finish with his right hand, and (C) he isn't giving it up once he starts his drive. They have adjusted to him. Now it is on him to adjust to them expand his game.
He also needs to get back to being aggressive and get to the line. He's only shot 2 FTs in his 3-game mini-slump. He was averaging 5.4 FT/gm in 5 games prior.
