Well everything has risks, yes that is true.
But the problem is there are no good FA quarterbacks on the market this year. The good ones rarely hit FA and this year in particular is terrible. FA is not an option IMO, for anything other than depth at that position.
Bradford, meanwhile, is good for depth too. But only if he restructures.
The only thing the Rams have going for them is the draft. It's their best hope, risks and all. Draft two for all I care and hope one pans out, I don't know. But they need to draft the position to get some hope. Wouldn't even surprise me to see them move up and take Mariota, for that matter, even if it takes a reverse RGIII trade to get it done. Rams need a QB that badly.
And I also pray they replace Schotty with someone who is a strong teacher of offensive football so we can see some consistent passing game production.
