I think what they are hoping for is that Blythe acts as the 6th man (starting weeks 1 and 2) with Noteboom, Allen and Demby as the depth. I have a hard time seeing Eldrenkamp, Neary, etc as anything more than practice squad candidates. If the Rams got it right with their draft picks then Williams, Lucas, and Dunn will be released by Labor Day.
My hope is between Noteboom, Allen and Demby they will develop two future starters. It would be great if all three did but it's unlikely. At
minimum they need one to become a starter and one to be a reliable backup. Their future salary cap in 2020 and 2021 depends on it.
