Best fight for these two if Diaz doesn't get mcgregor. Both very lanky with similar boxing styles and solid chins. I feel fight of the year on this one if it goes down.
I'm bias, but I don't think Ferguson is going to sub Nate, who has only been submitted once and that was by Hermes The Diddler Franca almost 10 years ago. I do think it would be a good fight though, especially considering their reach is "virtually identical"
