Tough call. They each have their strengths that can win you categories by themselves...for Whiteside, rebounds and blocks...for Butler high volume/percentage FTs and steals. I'd say build on your strengths, whichever of those two you're already better in is where I would go. I like to have my "gimme" categories that I can count on winning on most weeks and have a couple toss-ups...as opposed to being balanced across the board and having all my categories be toss-ups.

Since you're looking ROS, consider durability. Whiteside is a lot more likely to go down than Butler is.

They're too close to make that kind of a move. If someone is trying to sell Butler, tell 'em it's going to cost 'em and only do it for a 3rd rounder.
