Floyd Mayweather and his talks of "market value"

I apologize if this is a tired subject but I haven't seen it posted, even though it's old news. I just got a chance to read some of the PBF chats over at boxing///talk.com (June and August) and this guy just cracks me up. I am a huge Mayweather fan, but this guy is calling out people that he has no intention of fighting. "I want Judah" "Why won't you do the fight 50/50?" "Because Judah has to understand something called market value." This is such bullshit! Clearly the fight would be big because of both fighters, not just PBF. The same thing happened with him and Winky. The guy calls out fighters and demands rediculous purses, then settles on Mitchell? Is that really calling out the best? I would be fighting at heavyweight, but if I called out the best and demanded a billion per fight, should I be credited with "willing to fight the best at any time?" Don't get me wrong, Floyd is the man, and I think he could beat almost everyone he called out, but come on man! Make the fights dammit!
