MMK shot 69% last year. Do you think he's close to the offensive player Nate is?
Nate has a solid mid-range game and is a respectable three-point shooter (33% career). Evan hasn't shown the ability to score beyond shots close to the rim. He wasn't much different in high school, either, so this isn't a "role" situation.
Listen, I share your optimism. I think Evan will be valuable and that the coaches will find players who can fill in some of scoring we're losing. But there's just nothing to suggest Evan is going to be close offensively to Nate. Shooting 67% in limited minutes on limited attempts isn't convincing.
