#3 In-ring work
Then there's the actual in-ring work. Conor likely has no experience inside of a professional wrestling ring, and he'd have to train for a long time in order to prepare for that. Yes, he's never been shy about getting down to business and putting 110% into something, but we can't imagine he'll have the patience to do so when it comes to this particular form of sports entertainment.
WWE will likely want to rush him into a feud immediately after signing him because let's face it, they won't be able to keep it quiet for long and the WWE audiences can be ruthless. If McGregor isn't prepared enough which is an extremely realistic possibility, the matches won't be anywhere near the standards we're expecting.
Speaking of matches, he needs someone standing across from him.
