This week in “Press Row,” Jordan Breen and Sherdog contributor Andreas Hale discuss whether or not Jon Jones is the biggest disappointment in sports history, what he's got in common with O.J. Simpson, what Jones' second steroid test failure means for the legacy of Daniel Cormier and how it gives Conor McGregor, even before his “Money Fight” with Floyd Mayweather on Saturday night, even more leverage over UFC ownership group WME-IMG.

Breen and Hale also compare and contrast Jones and Mayweather, noting similarities in their historic greatness and fraught personal lives but the massive difference in discipline that has allowed Mayweather, forever drinking water in the strip club, to become an unparalleled promotional success as a boxer, while Jones has imploded due to his reckless indiscretions.
