What if Mayweather would've done something he hasn't done in his career and moved up to middleweight, for a fight with then-Lineal champ Martinez?
Both fought on HBO (at least, before Mayweather's departure to Showtime in 2013).
Let's say, the fight takes place either in September 2011 (instead of Mayweather-Ortiz and Martinez-Barker) or in May of 2012 (instead of Martinez-Macklin and Mayweather-Cotto).
No catchweight. Floyd comes in at 155lbs. Martinez comes in at his traditional 158-159lbs.
Who wins?
