You might be right about that Dieter, think it's a valid point.
Another strange thing here is that you have picks 1 & 3 both up for sale. So it's not going to net Dallas much to say they won't take a QB from a trade down perspective simply because moving all the way up to 4 for one of those QBs might, as
@Elmgrovegnome pointed out, backfire when SF moves up to 1 or 3 and takes Goff (I presume here that Cleveland goes Wentz).
So what I could see happening is Snead having a deal hammered out where the Rams move in to 4 IF one of Wentz/Goff is there. If not, then depending on how much they like Lynch's ceiling they could have a tentative deal worked out for moving ahead of Philadelphia or just sit tight at 15 and see if he makes it there.
If the Rams fall in love with Wentz or Goff and feel they need to have one of them, then I think 1 overall is most likely due to the Spanos/Kroenke hate. Whatever affordability you gain by going to 3 overall is probably squandered by Spanos being a prick, so why not just give up a little more and get to 1 overall where you control your destiny.
But who am I kidding... Rams will probably sit at 15 and take a defensive player because I never seem to be able to predict these guys.
