They'll need a running game to keep teams honest and for bad weather, but I'm ok with dink and dunk.
Getting 6 yards on 1st down with a dumpoff is still a plus play for the offense, and keeps them in favorable down/distance.

I think Davis/Jackson, Starks, and Ty can probably get them through...but yes, having Lacy would be nice. Starks' injury was bad timing.
They won a SB with Brandon Jackson and James Starks; they aren't SOL at RB yet.
