How in the world does Michael Lozada have a title shot against Chris John?!

[Texanballer]

I remember this guy getting a shot against Edwin Valero and i was like wtf? how is that, hes fought absolute cans, well he fought and got ktfo in 1 round. Then he fights more cans and now ha a shot against Chris John, which he will get stopped in or lose all 12 rounds. How does this happen?
