#1 It is a huge Publicity Stunt after all
CM Punk was one of the most bankable stars in the WWE roster. And the people at the UFC utilized his popularity to their advantage. Although Punk is taking his decision to join UFC very seriously, the same cannot be said for Dana White and Co. They announced his arrival as soon as he left WWE. That generated mega press coverage.
Similarly, Georges St-Pierre is the best welterweight fighter ever. And a potential comeback has been generating more news coverage than the entire welterweight division. This shows exactly what the bosses at the UFC want.

Punk is good for business.
And he has been in the spotlight ever since. He has not been able to prepare for his MMA debut right away and that might prove costly. But it will be foolish to say that Punk won’t be successful.
However ultimately, it is the name of the fighter that sells. That’s the harsh truth.
