So far this year, Haliburton's Usage Rate is actually pretty low, at 17.7%. That's a bit higher than Vassell's (13.2%), but still lower than DeRozan, Murray, White, Gay, Walker, and KJ. I see Haliburton more as a glue guy than a ball dominant guy, but at this point I think the Kings probably get better as he increases his usage rate.
