12. Stephen A. Smith
There have been no shortage of outspoken, opinionated guests on the Joe Rogan Experience, and Stephen A. Smith would be a welcome addition to the list. The US sports pundit is constantly vocal with his often unpopular opinions, and is certainly one of the more polarising figures in the industry.
The two would surely have made great conversation thanks solely on their big characters and personalities, but an appearance from Smith would be made all the more interesting since the two had something of a spat after Conor McGregor's return to the UFC in January 2020.
Smith, who was brought in to the commentary team after ESPN and the UFC came to a long term deal, called 'Cowboy' Cerrone a disgrace and a quitter after losing to McGregor in just 40 seconds. Rogan disagreed, accusing Smith of sh*t talking, and not knowing anything about the world of MMA.
Getting these two in a room to hash things out and talk even further about MMA, something Rogan is incredibly passionate about, would make for one the most entertaining, and potentially explosive episodes ever.
