I would consider Colledge at the vet minimum or slightly above. I would consider Davin Joseph for the vet min plus playing time incentives. Harey Dahl along the same lines although he is recovering from ankle surgery. Most of these guys are fringe starters at this point so there would be nothing hurt by signing one. Likely no guaranteed money and minimal cap effect.
Some of them will still be out there after the draft.
I don't think there is any chance of getting Zach Martin in the second..I know he has dropped some because of questions about playing tackle but you don't go from mid first to mid second without some major occurrence.
I am sure some of the board OL experts were all over Carimi too, but you know they won't ever admit it. Fact is he was considered almost everyone's fall back option in a trade down. Can't remember the number of mocks that had us dropping to late teens or early twenties for him. I had doubts about him being a great T, but really thought he would be able to move inside and be a 10 year starter type. Of course, the same could be said about John Moffit who has disappointed as well. He was another sure thing. Add in Konz and Zeitler and overall the Wisconsin OL studs really haven't stood out on the pro level.
