No. Boxing has been around longer then any other sport, It brings in millions of millions of millions of billions of dollars to the ppv market, it brings record number packed stadiums it makes alot of very powerful people very very weather, there would be a blood bath war if someone tried to sink boxing.UFC has been around a couple of days in comparison and is already starting to stale, with quick stoppages, horrible fights, and all their big stars losing. Also UFC is not a sport, its a tv show and sometimes PPV event like wwe. Mixed Martial arts is a sport, UFC is like circus with a roster of fighters much like wwe. Boxing also always goes through stale area's where you get a few good fights, and a couple mega fights. Then a fighter comes along and blows everyone away and the sport gets rejuvenated again. Plus we still have some of the best fighters of all time still fighting each other, with new legends taking their place. The only thing hurting boxing is the fact they dont let you see alot of big fights for free so its hard to bring a new audience, if they start to get in trouble they will bring boxing back to nbc, cbs and repeat the process.You want to see an up coming heavyweight who looks like he might run through the division check out David Rodriguez he has all the tools.
