3. Ricky Hatton
https://www.youtube.com/watch?v=8VFO2uceAk8 British boxer Ricky Hatton featured on Monday Night Raw in Sheffield, England back in May of 2009. The Hitman was booked into a wrestler vs. boxer match with Chavo Guerrero, but the encounter itself was somewhat disappointing. It lacked the drama and storytelling of a wrestling match, while it didn't have the speed or intensity of a boxing bout. In the end it got lost somewhere in between and finished all too predictably with Hatton knocking Guerrero out. While it was a nice idea to have Hatton actually compete, it only offered further evidence that the worlds of boxing and professional wrestling should probably remain separate.
