Why would I admit I'm wrong to a claim I never made? Although, I think it's fairly evident that Tilmon is more talented than Alexander based on the eye test alone, but it looks like stats are backing that up as well.
Tilmon was always described as a big with good mobility and footwork. But he's always been raw.
@Eric Bossi said he had 5star talent, but his motor dropped him. I'm sure he'd agree that he's outplayed his final ranking.
Alexander ended up being an undersized 5 that wasn't able to overpower and abuse people with his athleticism in college. Their ranking easily could be flipped in retrospect.
I'll bet now that Tilmon is drafted higher.
