To say 185 is the worst class is ridiculous. Especially when you have divisions like the Heavyweight division. If Sherdog and other MMA forums are anything to go by, I think it is more that a lot of people just don't pay attention to the division as much. It may not be has talent-heavy a divison as 155, but it is far from the worst.
As far as "greatest fighter" arguments are concerned with regards to GSP and Silva, people seem to ignore Silva's accomplishments at 170 and 205. He's been ranked top 5 over 3 divisions. Multi-division accomplishments are one of the major points of pound-for-pound arguments.
No they aren't. Multi-division accomplishments have nothing to do with P4P. The P4P ranking was created for Sugar Ray Robinson to fully express how much better he was then everyone else at boxing. Since there were divisions he would never enter. And this is boxing, where division hopping is easy since there are so many weight classes.
The fact is, GSP is 5 foot 10 and doesn't cut a ton of weight. He is the model size of a WW. Anderson is the size of a LHW and can cut down to MW. GSP has no more fat to lose to cut down, and would be at a massive weight, and height disadvantage at MW.
That said, GSP could probably dominate the MW division easily. Honestly, after watching what Sonnen did to Anderson, I think he would easily handil Anderson as well.
