Is Miller the most undeserving challenger..

Nope.

 

He is an easy knockout win for AJ. that's why he is going to USA for it, and he is very much undeserving too. Certainly one of the worst, if not thee worst challenger for unified titles in history.

 

He’s by no means a great challenger, but not even close. He’s more deserving than Szpilka, Duhupuas, Molina, Arreola, Washington, Breazeale(at the time) and inactive old Stiverne.

 

Look at Wladimir Klitschko's resume from 2004-2015.......

 

no

 

He has done more than AJ had done when he won the IBF title....

 

Miller is no where near be the most undeserving challenger. As people have stated Wilder and the K brothers challengers are a lot worse.

 

What has that got to do with anything? In his last 5 fights spanning just over a year he convincingly beat 5 solid opponents, two of whom gave Wilder issues. There are lots of people who have done less to deserve a title shot.

 

Probably not, that's a stacked field.

Fury and Wilder need a rematch, and Whyte the only one of the rest I could say deserves more, the rest is much of a muchness.

 

How many fighters have beaten someone in the current top 5-10?

 

Miller is a decent challenger. He's even better than some guys who have held a belt.
