Thinking about it, if these guys agreed never to fight each other then Jones shouldn't have agreed to fight Shogun. Rashad is right there and has no where else to go other than MW because Jones couldn't wait a year or two. Both of them know Rashad wouldn't keep the belt for that long and Jones got years and years of fighting ahead of him.
Sure Rashad probably told him to take the fight but that's Rashad being humble. Jones should have stepped back and said I'll beat some more guys, gain some more experience, and fight for the title down the line.
Luckily for Rashad, Jones is too confident and is going to get mauled by Shogun.
