Tough call. Both backs are really must sits, for different reasons.
Ivory is, without a doubt, the far more talented back, but the Raven defense, despite the up-and-down season, has done quite well against the run. Pretty sure they are in the top 5 for fewest points allowed to backs. Now, add to that the Geno Smith factor and who knows if Ivory will have many opportunities to touch the ball
Now, Mendenhall, despite his vomit-inducing 2.9 yards a carry, still is the "starter," due to the bizarre man crush Bruce Arians has for him. To me, he probably has the best chance of falling into the endzone, so I think I might go with him in that situation. I guess...
I'd go Allen and Wright for WR and Flex. Hicks just seems destined to never, ever get out of this funk. The combination of Eli's struggles and Hicks' assorted injuries has just made him so frustrating to deal with. And the weather report does not look good at all. Likely going to be in the low 30s with very strong winds. Could turn into a slugfest in the trenches.
