I think you're forgetting that Matt has a life outside of Fighting...Thats what makes his legacy so special. He's not one of these Fighters who does nothing but fight, and thinks of nothing but MMA. He's not one of the guys who will crumble when they can no longer compete because who they are is identified by what they do in the Octagon.
You have to remember, for Matt this is more of a Hobby then it is the Career of his Life. He also is a farmer, and he also runs his own gym...His legacy has surpassed so many...and yet he NEVER set out to create one in the first place...thats whats so ironic...with all the others focused on nothing but creating a legacy.
For Hughes is simply just happened that way, and whilst it lasts its brilliant, and once its over he can move on without a tear.
In many ways, I reckon lots of the Other Fighters who have recently been blathering about holding multiple belts are so desperate its...a little bit tragic. THAT is unlucky...unlucky that two guys, Georges Saint Pierre, and Baby Jay Penn, and Anderson Silva even...who dedicate their whole life to nothing but MMA...combined cant manage to create what Hughes did in a hobby almost by accident.
Besides...Whose counting Hughes out? I mean, after he has smushed Serra, he might yet go to fight GSP, or Thiago Alves for the title...and then would he not be in a position to challenge Anderson Silva? Just think...two more years, perhaps, six more fights...and He'd retire with Two belts, the first and only to hold two consecutive at the same time. Have Avenged Alves, Have Beaten Georges Saint Pierre for the Title, have maybe defended it after that also. Perhaps had a warm up fight in Middleweight, before smushing Silva, and then possibly defending...and so would have had THREE Reigns with defences in the Welterweight Division, and One further reign with defending in the Middleweight division.
We dont know what might happen after Serra gets smushed...or as this isnt probably that huge a deal...he may just retire on a win...people seem to think he has something to gain, or something to lose...Truth is he has neither...His Legacy stands no matter what now, perhaps it can be extended, perhaps he doesnt feel the need. who knows...but I wouldnt say its Unlucky
