Flex: Beanie Wells, Toby Gerhart, or Brandon Lloyd? ?

[steelglam]

Which of these three should I start at flex this week: Beanie Wells vs. SF, Toby Gerhart @ DET, or Brandon Lloyd @ SEA?

Normally, I'd roll with Wells, but he's going up against the number one rush D in the league...and that D has yet to give up a rushing TD this year. As for the other two, they both are going against middling defenses (Detroit's rush D and Seattle's pass D are about lower-middle of the pack). So, in that case it would be a choice btw. the more unproven RB with more upside (Gerhart) vs. the proven WR that is consistent but does not have as much upside (Lloyd).

What do you think? I think I'm leaning toward Gerhart...he did pretty good last week. Wells seems too risky of a start.
