Great article. One thing I loved is how it talked about how Henry's work to position himself for rebounds cost him on the defensive end and stunted his shot-blocking ability. Also, since about this time, the work he's put in on his defense and shot-blocking has been apparent.
Henry had 24 blocks in our first 18 games, an average of 1.3 bpg. Since then, he has 20 in the past 9 games, an average of 2.2 per game. He's been more aggressive in defending opponents and using his size to alter shots. In addition, it really hasn't hurt his rebounding, he's still pulling down 10.5 per game over that span.
He's also been committing more fouls in that span (2.8 in past 9 games, 2.3 in first 18). Again, being more physical on defense, and doing so without fouling out. All of this tells me he's responding to the coaching staff. Good sign for both Henry and for the staff.
His game has deficits. His three-point shooting especially. A guy with his size and consistent form should have little problem with shots being contested should be able to hit around 35%. But again...a positive in that over that 9-game stretch, he's hitting 34.6% (9/26) beyond the arc. Maybe a sign he's picking shots better or gaining confidence?
As far as the easy rebounds, I would agree that Henry makes rebounds look easy. There are two reasons for this. First, he does get great positioning which allows him to pull down many balls uncontested. Second, he doesn't have the kind of upper body strength many of the more experienced players have so when a board is contested, he's not as likely to pull it down. The former is a great skill and it's impressive that a freshman has such a feel for that, the latter is a problem but can be easily rectified with coaching and time in the weight room.
The biggest issue with Henry is his efficiency. That should improve with better shot selection and having more talented players around him. Whether it happens here or not remains to be seen.
