yes but we don't always draft OG's to play OG... i think we'll look at some of the bigger tackles e.g mankins and see if we can convert them to OG
"Bigger tackles?" Mankins is 5 lbs heavier than Light and the same height. He's 5 lbs smaller than Kaczur & Vollmer, the same height as Kaczur.
Scar looks for experienced LTs with good technique, nasty on-field attitudes, smart, disciplined, capable of pulling or getting out to the second level and getting in front of a defender. His five OL drafted in Rds 1-3 were all 6-3/6-8, 305-319 using Combine/Pro-Day numbers. If NE needs a prospect who might need to start right away at OG then throw out Vollmer's 6-8 as an outlier and you've got 6-3/6-4, 300-320. Don't look for the highest rated tackles from draft sites, look for their mid-round kids:
Danny Watkins, Baylor, 6-4/310 -- 12 starts in Big-12 before 2010 season, played in all 22 games at the juco level, but no start data (though he got recruited by Baylor so you can guess).
Jason Pinkston, Pittsburgh, 6-4/308 -- 28 starts before 2010 season (converted DT).
James Carpenter, Alabama, 6-5/300 -- 14 starts in SEC before 2010 season, juco transfer so you know he was starting at the lower level to get SEC attention.
Benjamin Ijalana, Villanova, 6-4/320 -- 39 starts before the 2010 season
Clint Boling, Georgia, 6-5/304 -- 36 starts before the 2010 season
All of the above are college LTs (or, like Boling, was moved all over the line, including LT) and currently projected to rounds 2-4 by NFL Draft Scout. Villanova is in the FCS (1-AA) sub-division which doesn't improve his odds, but the other four play in BCS conferences. Watkins and Carpenter may start at a disadvantage due to their juco background limiting their experience at the higher level, but Vollmer only played OT two seasons so I don't think it's insurmountable. All were All-Conference First Team, save Watkins who was Second Team.
It's a small draft pool, but in 2005 there were exactly two kids who met the general requirements and were projected to the same rounds by NFLDS - NE drafted both of them.
