He's definitely a candidate but Kyrie Irving has the advantage of playing for team with fewer scorers.
Marcus is taller... It's weird because I really wanted the Rockets to find a way to snag Williams and instead we seem to have gotten a guy who is very similar... I can't wait to see these two matchup...
Combine measurements actually have Derrick Williams being the taller one by a quarter of an inch, although they're listed at the same height with shoes on.
