Cenas the only big draw that's full time in US wrestling. A case can be made that Reigns, Orton, and Ambrose are draws too on some level, they probably are.
Beyond that though, KO or Jay Lethal are not draws. On a scale where Jay Lethal is a 3/5 draw, prime Lex Luger is a 7/5.
Okadas a great worker, but the guy lacks charisma to me.
I put Lesnar at #1 easily. Nothing draws the viewer's attention like he does. AJ at #2, he should be their new Seth/DB workhorse.
Brock:
Ring- 5
Mic- 3, very limited but knows it, so extra points for not extending himself beyond his limits and sounding stupid.
Draw- 4.5/5
Gimmick- 5
AJ
Ring- 5
Mic- 3.5/5
Draw- 2/5
Gimmick- 4/5, he's a believable regular guy, the fans buy into it even if it's not larger than life.
