Outside of QB, LT is the hardest position to fill. Many teams need OT's. The overall quality in the league is lacking more than any other position. My fear is that we're going to see a run on OT's with Campbell, Membou, Banks Jr, Simmons, Conerly Jr., and Ersery all going in the first round. If a team has a vital need at OT, they MUST draft OT in the first round. Its not sexy or exciting but a hole at that position will tank your season no matter how good the rest of the roster is.
All these mock draft websites rate players differently and create a false sense of who might be available at #38.
I'm hoping for the trade down even if Carter is avail at #4. His presence will likely lead to a better offer from someone in love with him. Ideally I'd like to trade down to 6-10 and pick up an additional 2nd rounder+ in the process and take whoever is they think is the best LT.
