I think if you're looking to play it safe (i.e you feel like you should win this matchup) you go with Miller. If you need the homerun play go for Riddick as he could find the end zone multiple times today in a shootout with New Orleans
DET vs NO should be a shootout, but seems like Riddick is only good for PPR.
Murray is TD dependent, but Bills are middle of the pack again the run in what should be another high scoring game.
Miller has highest floor, but I just dont like anything about HOU offense.
