The Rams have stumbled across a really good OL combo and they need to keep it.
There's only 1 guy that will demand a high value market contract and that is Dotson.
It won't be terrible to retain Shelton and Jackson.
But, the key to the Rams offense is to open holes for Williams and to keep Stafford upright. Don't do both of those things, and that O is dead in the water.
The Rams do NOT need more skill position players. But they DO need to keep that Oline intact. Spend the money there. Then go after the best Edge money can buy, and then let everything else fall into place as best it can.
I think Dead and Alyo would agree that some really good CBs are going to be available to the Rams in rounds 1 and probably 2. So, we can solve that problem fairly inexpensively.
