The LA Clippers acquired John Collins from the Utah Jazz, knowing his veteran status in the NBA. He has eight years of experience, going into his ninth season, which means he has been a part of eight training camps, eight media days, and eight preseason rosters.
Furthermore, Collins has seen a lot of talent on the Atlanta Hawks and Utah Jazz, some of which the world never got a full display of. Others may be recognized by the NBA community, but still on an underwhelming level.
A few of the stars that had to have shocked Collins were Trae Young, Lauri Markkanen, James Harden, and Kawhi Leonard.
