Sorry to double post, but I'd like to mention just about the only left tackle upgrade the Pats might have gotten for a good value these last couple of years was Jason Peters, who the Pats must have scouted because they selected Cedric Cobbs from the same school (Arkansas) in the late fourth that year (2004). Roman Oben was traded to the Chargers by the Bucs in 2004 for a 2005 fifth, but he is at Matt Light's level, adequate.
Peters ended up going undrafted and was signed by Buffalo of all places. He was on the roster as a blocking tight end in 2004, switched to right tackle in the off-season and played the season at that position, was hailed as a young up-and-comer coming into this season and was eventually switched to left tackle for Wayne Gandy after Buffalo's bye. The hearsay I've heard is that he's given up two sacks in his career to this point.
Peters played tight end next to right tackle Shaun Andrews (now a Pro Bowl right guard with the Eagles) at Arkansas, which tells you something about his natural athleticism (listed weight 320). Reasons the Pats might have passed on him to draft the likes of Cedric Cobbs, PK Sam, and Christian Morton were that Peters scored very low on his Wonderlic (9, where Pats lineman average a very high number, and offensive lineman in general do well) and that Peters was adamant coming out that he wanted to play tight end in NFL, only later switching to tackle when he realized he could make more money at that position. Obviously the Pats are not allergic to dumb but devastating blocking tight ends (Daniel Graham) or tight end to tackle conversion projects (Tom Ashworth) but maybe the low score and the other thing were indicative of an existing attitude problem. He certainly seems to have his head screwed on right now however.
That's it. One tackle I can think of, from three years ago, that the Pats had a legitimate shot at and that would be an upgrade over Light. Where is this shiny new left tackle going to come from if our lowest pick is 24? Maybe Box is right and a full offseason of body work will be beneficial for one of Light/Kaczur/Britt, but otherwise, even assuming we are blessed with a shrewd selection of a physical freak like Peters, that's (at least) a two year process before Light's out of the starting lineup.
I also can't see them moving Light over to RT over an improving (hopefully!) O'Callaghan when its being rumored he's having trouble maintaining adequate weight for the more agile left tackle spot.
