Monday's poll: Who is the best pound-for-pound fighter in the world?

Floyd Mayweather's domination of Juan Manuel Marquez in Monday's fight has led some to say it shows he is the best fighter in sports. Others disagree, saying Mayweather is the best dancer in sports, but ducks tough competition and is afraid to stand and trade punches.

Then there is the MMA crowd, who say no boxer would stand a chance against a top MMA fighter.

So, who is the best pound-for-pound fighter today? Vote in today's poll, then leave a comment letting us know why you voted the way you did.
