I can't tell if the second part of your post is an attempt to backtrack giving Warmack sole credit for SEC experience, but Warford of Kentucky has it as well. It doesn't make sense to list it as an advantage for Warmack considering they both play in the SEC.
As for being the most coveted guard if Warmack weren't in the draft, that's not true. That'd still be Jonathan Cooper. That being said, I can see your point about the value of Warford in the second versus Warmack in the first. That being said, I don't really want to take Warford in the second. The entire point of taking Warmack wouldn't be that guard is our top need, but simply that it is a need and Warmack is a very rare caliber prospect. Warford is a good prospect, but not rare, so I'd rather take an offensive tackle(presuming there hasn't been a run on them) in the second than Warford.
I've watched a lot of tape on both Warford and Cooper, and I prefer Warford. There's still a lot left to the draft process though which could ultimately determine who the better prospect is.
