I think the word ducked is overused, I think fighters chase the biggest fights possible. Honestly Mayweather is returning after 17months off? I don't think he should be fighting Mosley or Pacquiao. IMO taking Marquez is a huge risk, and I think he could be more dangerous than Mosley for Mayweather, because even though he isn't physically faster, IMO when timing and everything is put into play he is faster than Mosley(IMO his handspeed is the same if not faster), Marquez definitely is the better boxer, he actually has a jab, he's a vastly superior counter puncher to Mosley, the only two things he has going against him in comparison to Shane is inferior durability(I think this is a big concern, but Mayweather doesn't hit as hard as Pacquiao and JMM handled Pacquiao's power, for the most part, pretty well). The second is size, and Mayweather doesn't really use size to his advantage, and Mosley will only have an advantage with this when he would have Mayweather on the ropes because in the middle of the ring I think Mayweather would pick Mosley apart, whereas I am not so sure of that against Marquez.
