That is absolutely preposterous....if you think that Conor is the type of person that fears any fighter, you are crazy. Aldo was considered a much harder fight than Frankie. Mendes was considered a much harder fight than Frankie and that is why he received the nod at 189 (Lorenzo was told that Mendes was a harder hitting version/more dangerous version of Edgar and thus received the nod). Additionally, Frankie was offered the fight at 196 and Conor accepted but Frankie didn't.
Sure, there are fighters like GSP that take a very egoless, calculated approach to fighting and care about winning more than anything. Conor is not like this, he believes success lays in his belief, ability to engage the law of attraction and does not operate like we do/the majority of fighters do. There is ample evidence of this in not only his tweets, his interviews but his calling how the fight will play out/when he will finish/etc. I also think the "troll tweet" ('UFC 200 is on again - thanks Dana and Lorenzo') was Conor trying to engage the law of attraction and not troll (i.e. you must speak it/put it out into the world for it to come to reality).....regardless of what we think of the law of attraction, if it i bogus or not, it defines Conor and as such he would not fear anyone, reasonable or not.
This whole "Conor is scared of Diaz", "Conor is afraid of Frankie" is absurd. I honestly don't think he is interested in either of those fights because the money isn't as big as other bouts available to him. Additionally, his team and he don't want to cut to 45 again (as pointed out by Gunni on The MMA Hour) and who can blame the guy when he can make more money taking other fights and not having to go thru that hellish cut. After 194, his coach said that was the last time that you will see him at 145 and I have reason to believe that will hold true. Im sure the UFC wants him to do that and as such, this is why we are hearing about the Mayweather bout which further proves my point that Conor is afraid of nobody, as beating Mayweather in boxing is more difficult than Conor beating Jon Jones in MMA...it is simply where the money is and that is what motivates the man.
