I think it's more that Vince was a good risk taker more than being a genius. Some of the gimmicks and ideas he's pitched in the past make me question his sanity. A lot of the ideas for matches, ppv's, gimmicked matches, have come from the people who work with Vince. Like Pat Patterson being the one who came up with the Royal Rumble idea. Vince just had the balls to run with things.
Now Vince is surrounded by yes men and no one is there to filter the bad ideas. That's what most ex-WWE employees say.
