I'm really low on Barrett right now, I just think he gets too much credit for "looking the part" on both offense and defense. He appears to be athletic and explosive, but he still stinks at defense and is horrid at finishing his drives.. He just isn't functionally athletic and he has bad touch. The numbers hate him and I can see why.
But I do think Barrett could have the most trade value out of the 4. If I had to rank them in pure talent and their ability to be a star player I'd go:
1. Simmons
2. Ayton
3. Barrett
4. Herro
But I think the trade value is more like:
1. Barrett
2. Herro
3. Ayton
4. Simmons
Simmons also has the most risk associated with him, but if we get the most picks by taking on Simmons....I like it. The proposed Bobby Marks deal is way more preferable than the MIA deal IMO. You get more picks, a better "premium" asset IMO, and don't have to take back a bad contract. I would not mind if Ayton was sent here and Simmons to IND either. If I had to bet on who makes the most all star teams out of the 4, I'd pick Ayton even though Simmons has a higher ceiling.
