I lean Brogdon, but I guess devin booker being in/out could play a role

If you are hurting for points, Warren is better, but his stat set (as Bruski would say) isn't great. Look at his stats from the two previous seasons... he gives you very few steals, blocks and 3s. He's come out hot, but even so he's not playing a lot of minutes despite Ariza being on a cold streak (creaky bones need time to warm up). But once Ariza's shot starts to fall, and Warren cools off a bit, he might not be in the top 120. Season long I'd rather have Brogdon.
