....Sometimes... In the modern era out of kayfabe accomplishments reflect kayfabe characters... And that makes Rollins so easy to book. If you want to go the old school route he's sort of the new school Dusty Rhodes, the guy who works his ass off every night to earn his paycheck and put on as great of a performance in victory. If you want a sports perspective he's an easy draw with his precision striking, quality aerial offense and a devastating finish. If you want sports entertainment you can package all that into an assassin type character and play off the badassery in that commercial.
It all seems so easy because when you watch his ringwork his character speaks for itself...
(On top of that "the guy" who brought me into wrestling was Jeff Hardy. Not some elaborate character, just the dude who wasn't afraid to do 10 dives a match to try to beat his opponents lol)
