I'd be happy enough with Charlie V, but I wouldn't deem him a first option signing.
Villanueva isn't the ideal type of role player -- His defense is poor, he's inconsistent, mediocre efficiency offensively, and he needs the ball in order to be effective. His rebounding is solid.
I prefer more defense, more reliability (consistency), better decision making, less need for the ball in their hands, more efficient scoring. That type of stuff.
Still, he'd be an interesting player to add to the equation. Not a first choice, but a solid choice all the same.
