The Ravens trading down does make some sense. We have 3 key positions we need to address early in this draft. They are pass rusher, corner, and LT. A trade down and picking up the 33rd pick, which is top of the 2nd round and pretty much a first rounder anyway, would allow us to do that.
In Mayocks draft the Dolphins took Lawson a couple picks before us but if we could trade back and actually get a guy like Lawson or Conklin at LT there should be good options at the other 2 positions sitting there for us in the 2nd.
I'd prefer we not take the risk by trading back and getting stuck in limbo a bit like what happened in Mayock's mock but the reward is there if everything falls into place (sort of like when Jimmy fell to us in the 1st and Torrey in the 2nd).
