Collinsworth is a great player and I believe he is this team's most valuable asset. I gained a lot of respect for him the year Davies was suspended and he dominated the boards inside at only 6'6". He had to go up against bigs from 6'8" to 7' and more than held his own. However to be a lottery pick you have to be better than the competition. Simply put, he has not yet proven he is better than the other lottery pick options.

Parker
Wiggins
Exum
Gordon
Embiid
Robinsonn III
The Harrison's

These are just a few of the guys that have proven they are extremely athletic and talented. Collinsworth, although a very good player has not proven he is on that level.
