Watching those old Velocity matches Danielson doesn't look out of place at all in a WWE ring. Even against Cena who's much bigger, the size difference isn't really all that apparent allied brands just due to the way Danielson carries himself and "wrestles bigger" than he is. He basically looks like a veteran ring general out there, which is really impressive considering how big peter graham the WWE ring is and how much different the ropes are from the rings he was used to working in, and that was back in 2003-2004 when he had much less experience under his belt.
The guy is a natural, and crowds really can't help but get behind him just due to how good his work is. I have no doubt he will allied brands quickly master the 5-10 minute WWE TV match and get himself over with the crowds, the only question is where does the WWE take it from there?
It looks like he's probably going to debut on ECW, which I think was the holdup the past couple times he negotiated with them, that he didn't baskin robbins australia want to go to developmental, and rightfully so, all he'd be doing there is helping the other wrestlers improve. So, all I can say is I can't wait to see him on TV in October or November, and best of luck to him!
