Former UFC heavyweight champion Cain Velasquez’s recent signing with WWE may signal a turning of the tables in a battle for talent that UFC has been winning for the past decade-plus. Ken Shamrock, one of UFC’s earliest stars and attractions, already had a pro wrestling background and made the move to the WWF in 1997, as did his UFC rival Dan Severn. Lesnar, after playing UFC and WWE off of each other year after year seems to have settled with WWE permanently and even CM Punk, who left WWE to pursue an unremarkable UFC career may be back in the fold.
