I know Anthony Davis has a higher offensive ceiling than Noel and without the injury history
But I'd like to say that Noel is pretty close defensively
Lets pick Bennett and Alex Len though
I actually think Noel was a better all around defender in college than Davis. At least he had better stats and had to do more things because the perimeter defense was terrible, without a lockdown defender like MKG to help him out, Noel had to do it all, blocks, steals, on ball defense, take charges, etc.
The perimeter defense Davis played with was good enough that he could just roam the whole paint and even out to the 3 point line sometimes to block shots. Also helped that Davis had a big body like Jones to do the dirty work under the basket while he was roaming for blocks. Noel really had to do everything for that team.
Offensively he isn't really close yet, but he should be defensively if he is healthy.
