Watch Brian Campbell break down the fight on the Morning Kombat channel: https://www.youtube.com/channel/UC9Qy3sHrr5wil-rkYcmcNcw Internet star Jake Paul proved experience matters in his return to pro boxing on Saturday in the co-main event of the Mike Tyson-Roy Jones Jr. pay-per-view. Paul (2-0, 2 KOs) scored a trio of knockdowns en route to a brutal second-round knockout of former NBA star Nate Robinson in their cruiserweight bout inside Staples Center in Los Angeles. Although he held advantages of four inches in height and 13 years in age, it was Paul's significant edge in boxing training that proved to be the difference. Along with having made his pro debut in January when he finished fellow YouTube star AnEsonGib in two rounds, Paul has done nothing but train this calendar year. The 36-year-old Robinson (0-1), on the other hand, started boxing for the first time in August after calling Paul out and the results showed.
