Both are on the wire right now and I'm leaning towards Crash because of the more stable rotation of Brooklyn. Here's my team though if it helps.
i'd pick up both if you could but wallace before thornton. the worst players on your team are valanciunas and sanders, and i would drop them for those two if you can
If I pick up both I think I'll suffer on blocks...I'm already it great on blocks but Jonas is pretty consistent there..Sanders I'll eventually drop but he just put up 10 blocks.
