No idea, but I think the difference between 15th and 35th on a draft board really isn't very significant, but especially this year. Why do some like THT? They see a switchable guard whose body could handle mismatches and would be a plus in the pick and roll nba.
And he's young, so maybe he ends up developing his playmaking ability and you have a role player.
Now, many would swap him with huichimara, and have THT in the 35ish range. He trades huichimaras production in college but worries his processing and sluggishness on D will get him eaten alive in pick and roll defense, negating his developed offense.
The guys really from 11-35 are either productive college players that could get eaten alive in modern defense or a guy that accomplishes one specific thing and you roll the dice and hope he develops others.
Do I think Ayo could have risen? I don't know, I think some would have him higher and some lower. Some love Jontay Porter, some would point him as undrafted. Depends what happens to a team in charge. I think Ayo would be a 2nd rounder, and more than likely THT will be a 2nd rounder.
