Amazing things happen in the draft but I think it's wishful thinking to believe Lawson, Rankins, Lee or Floyd will fall to 29. I'm not sure which Jenkins you mean. Ogbah is very raw and may become a rusher at some point, but the Cards need 2016 help. Dodd could be there. He is also rough. He doesn't seem to have that burst a guy like Feeney has. He's closer than Ogbah, but hard to imagine him having 2016 impact. BTW I know getting immediate help from a drafted edge rusher is rare. If you want to gamble on a developmental player and write off next year take Jaylon Smith. He may never play, but if you win; you win big!
I think history supports the fact that speed rushers are the most likely to have immediate impact and that's Floyd. He's no sure thing, but he's the best shot. They should sign Freeney now. They should have grabbed a FA like Hayes. That failure has left them here.
