I don't follow the NCAA, and basically have no idea who Cole Anthony is, but one thing I've noticed is that the track record of "unproductive, but physically gifted" guys, as measured by something like BPM, is pretty abysmal.
Anthony has a +5 BPM. It's almost impossible to find a freshman to be drafted with a BPM that low to have gone on to NBA success. As far as I can tell, the list is like Jaylen Brown, Zach LaVine, Andre Drummond, and that's about it. That's not the end of the world, but would make me less than eager to use a top 5 (or 10) pick on him.
