Re: G in the 1st round?
I can't see Warmack dropping to 27. I don't know much about Cooper.
There are a ton of good guards in this draft so it isn't necessary to take one in the first round. David Quessenberry (San Jose) shined at the Senior Bowl and will probably be a OG in the NFL. Larry Warford (Kentucky), Hugh Thorton (Illini) and Bryan Winters (Kent State) all looked good at the Senior Bowl as well.
Another thought would be to take a tackle and move Newton inside.
