I think they've had a very good offseason thus far. They resigned their biggest FA in JPP. They made a huge upgrade and filled a need at outside WR with Marhsall. They upgraded their TE group with Ellison.
At worst, with no additional moves, they are the same at OL with potential for improvement. But that's a pretty good spot to be in going into the draft.
Like I said, with the Fluker and Jerry signings they can now look at signing one more Vet and take a draft pick in the first few rounds, at least one of which should be someone that can compete for the LT spot.
With that, they'd have 7 players legitimately competing for 3 starting OL spots (assuming Pugh and RIchburg are entrenched in their spots). Competition is the best way to elevate these guys.
