Jackson named the best MMA fighter regardless of weight class

Quinton Jackson, former UFC champion, revealed who he thinks is the best MMA fighter regardless of weight classes.

"I think Dana was talking in general and overall. He wasn't saying who is the best fighter in the last 5-10 fights or the last 1-2 years. He was talking in general, you know? I know Jon Jones is a dirty fighter. But his one loss was unfair. I watched that fight. And Islam is really good and everything, but he really lost one fight," Jackson said in an interview with Demetrious Johnson.
