WrestleMania 35: 5 Biggest Reasons why Vince McMahon won't let John Cena wrestle

#3. His schedule is far too hectic

John Cena transitioned into a part-time role around October 2015 and hasn't turned back since. There's nobody who can tell you that he hasn't earned it because he carried the company on his shoulders for a good part of a decade.

Looking to explore his options in Hollywood, Cena took a similar path to The Rock and began to work his way up the Hollywood mountain. Slowly but surely, he began to get an increasing number of high-profile movie roles and that's something that is going to keep flowing.

With his extremely tight movie schedule, Cena likely doesn't have much time to get back in the ring and even if he does, he may be stopped by his insurance company. This is exactly what happened to The Rock. After getting injured at WrestleMania 29, his insurance company basically told him that enough was enough.

While Cena is not fully retired, he's only going to wrestle with decreasing frequency.
