If teams don't think of his as a potential threat to score they won't guard him. If they don't guard him, they can help off of Morton without being penalized. The whole point of Purdue's offense was to dump it down to Zach and if he gets doubled or triple teamed pass the ball to a back cutter or out to a perimeter player for the open 3.
Teams laid off of Morton this year and he took 3.7 shots a game and made 1.2. Two years ago he took less than 1.8 shots a game, making .8. I'm not talking about 3s here. I'm talking total shots from the field.
My point was that even if Morton shot 44% form the field (compared to 32 %), he'd still only make 1.6 baskets a game. In my view teams still wouldn't guard him, because he doesn't shoot unless he's wide open.
Lets just say hypothetically that Morton was an effective scorer and teams couldn't leave him. Wouldn't that make things not only easier for Zach but also Loyer, Gillis or Smith? Wouldn't it help them get more open looks if teams had to "pick their poison" and occasionally double off them as well?
