The OT need is more about depth.
Yep, no need to use a high pick on OT IMO. Find a guy in the 4th to develop (Ted has a ton of success in the 4th Rd picking O-Lineman). You're starting 5 is coming back next year with a really nice 6th in Tretter, and who knows maybe you let him and Linsley fight it out in TC for the center spot.
