The Skura commitment comes as a bit of a surprise to me, since he just received the offer over the weekend. Also, Duke is in the final running for a few more 2011 offensive lineman, notably Marc Mustoe, Cody Robinson, and Shane Mertz, all of whom visited campus recently. There are a few other offers out there, but those are the three I'm most familiar with and seem to all have serious interest in Duke. Skura makes the third OL commit, along with Lucas Patrick and Marcus Aprahamian. If the staff can land one or two more out of the outstanding offers, it would make for a very nice OL class.
Don't forget there are also 2 pretty good-looking young offensive lineman on campus this summer in Laken Tomlinson and Takoby Cofield. Matt Luke is doing a great job recruiting and coaching these big guys.
The staff "really wanted" David Helton, so I think they see him as a potential stud LB for the future. Britton Grier, from Charlotte, is another LB commit in the class of 2011.
Blue Devil Nation is running football articles for free, so you can read up on several of the commits and recruits above.
