Conor Mcgregor: post Mayweather fight and the future of the UFC

The Conor Mcgregor vs. Floyd Mayweather fight was a historic event, albeit a bit of a Spectical, Conor's first four rounds in the ring were surprising and perhaps uplifting for Mcgregor fans, the fight had an obvious outcome. Despite all that the event managed to bring in $6.5 million pay per view buys at a hundred dollars a per viewing which is an estimated total of $650 in gross revenue. From that Mcgregor managed to earn himself an estimated $30 million with Mayweather earning approximately $100 million. Conor's days in the UFC would earn him anywhere from $1 million to $5-10 million
Given the brutality involved in MMA, it is Difficult to picture "The notorious one" coming back to the octagon. Would Conor be willing to take more blows to the head and risk further injury? One doctor was quoted saying

"Byrd's calculation to call a stoppage was likely not based on signs of fatigue, but rather signs of traumatic brain injury. Ataxia, or dizziness and loss of balance, is one of the hallmarks of concussion, a type of mild traumatic brain injury. Fatigue may cause sluggish and slow movements, but does not cause the imbalance and poor coordination exhibited by McGregor in the 10th round. Being wobbly, in the setting of pugilistic trauma, will always be treated as the result of head trauma and not as fatigue. To let a fighter continue on would be grossly negligent."

The fact that Conor may not return to the UFC is terrible news for the company, given that he was their main attraction and top earner. On top of that if the UFC does get McGregor back they will likely have to offer him a much larger purse each fight in order for him to even consider it. This UFC shrinking profit margin is going to be an issue for the company in the coming years.
As of this moment, the UFC does not have any fight that can attract the same kind of audience the McGregor could this issue is exacerbated by the fact that Jon "bones" Jones failed the post-fight drug test (follow for another post on that topic) after defeating Daniel Cormier at 214. These 2 titans were unequivocally the two biggest draw for fans of the Octagon, The majority of UFC cards put together this year by the UFC have struggled to break 300,000 PPV buys. Suffice it to say 2017 has not been a kind year for the company and the future is looking bleak with no Ronda Rousey insight as well.
