Like most others I disagree with Paulo ... pulling guard with any top fighter nowadays seems to guarantee a sound pounding. By now every elite fighter knows "old school BJJ" enough to defend all but the Maia / Jacare levels.
Not to mention pulling guard against a guy who no one has ever taken down is pretty damn hard. Most likely they'll end up flopping and making asses of themselves like Leites and Maia against Andy.
IMO the way to beat Jones is to counter his Greco and Judoesque upper body centric style with someone who has a VERY fast shot. Yeah he's faced wrestlers, but he's faced slow, plodding, drive through wrestlers. He has not faced a Sonnen/GSP/Phil Davis type guy who will neutralize his reach with a fast deceptive shot.
In my experience, guys with great greco are inherently weak against a fast mixed in shot. It's one of those rock/paper/scizzors thing ... they train their whole life in the clinch and upper body misdirection, clinching/driving through with them is suicide. You need to take their legs out, fast. Their reflexes aren't as tuned to that as a top freestyler.
