How are you defining explosive? Sword lowers his shoulder and steamrolls to the basket, and he happens to have a knack for getting his guy to move his feet. That's awesome. Without that, I don't know if MSU would have won a game the last 3 years. But Malik turns on a dime and dances through the lane and somehow gets into position for a layup when he decides to turn it up.
"Runs to the basket" shouldn't be the first box you check for explosive. Malik has feet, and despite a toe injury I think he's put that on display.
I've heard stuff from people on whether he'd be back or not, that's obviously a personal choice he'll make, but he'd be a first rounder if he left. Fans shitting on him because they've brainwashed themselves that Stans/Rays' players are decent isn't productive or correct though. If he leaves in March, that's awesome. He was worth some wins.
If I was Malik, I'd come back, get IJ to transfer, and make it where Howland had to start me at the PG exclusively. That's me. Couldn't fault him for taking a signing bonus and 6 figures to go learn from the best coaches in the world instead though.
