Why does Canelo hold onto the MW belt?

[stephenmc]

It seems like the belt brings him more problems than what it's worth. He claims he's not a true MW and he even said before the Cotto fight he didn't care if the fight was for the belt or not. Why not just drop it? It'll save him money and questions about GGG which you can tell is starting to annoy him. The questions about being a MW but fighting at 155 is also starting to annoy him. The MW belt doesn't help sell the Khan fight. The numbers would be the same with or without the belt. He put 30k ppl in a baseball stadium and 2 mil views without a belt. He's already established so how does it help him by holding onto the belt?

Casual fans........
That's what the belt brings, also a bargaining chip...
Hardcore boxing fans know he's not a real MW nor is he the MW world champion, but on paper he is, and that's what the casual fans look at... Without the belt, boxers would say well why would I want to risk this fight, casuals will say, who is he, he doesn't have a belt or o he's the fella who got beat by Mayweather...
The only people who will buy/watch a fight without a belt would be a boxers fans from their own country (Mexican this time for example) and hardcore fans.....
