Wow, that flex options are tough, my first choice would be to go with Thomas, thou the Browns have been playing real tough D this season... He'd probably be covered by Haden all night.
Graham and Cruz are not bad options, just don't want to have one of those games where they are not a heavy part of the offense... If you ran with thomas all year, I'd stick with him.
RB... Morris and Martin.. I would say Lynch for sure, but, SF proved to everyone last week their D is truly legit. Well, they've been proving that ALL year! lol
Good luck... If you have time... viewtopic.php?t=532908
