Face it Khan-Bradley is not gonna happen. Arum is not gonna risk his newly signed racehorse against a dangerous GBP fighter. So the only way to determine the next "lineal" champion is to compare resumes. Assuming Khan also beats Peterson can Bradley even make an arguement?
Only considering top 10 ranked opponents fought at JWW it should be safe to say that Kotelnik, Paulie, Maidana, and Judah>>>>>>Holt, Campbell, Witter and Alexander. Technically McCloseky was ranked number 10 prior to fighting Khan but I won't include him.
The names alone should tilt it in Khan's favor but also consider
1. Kotelnik arguably upset Devon in his hometown but got dominated by Khan and Devon is supposedly Bradley's best win.
2. After arguably being robbed against both Lucas Mattyse himself stated "Judah was far better than Devon" http://www.boxingscene.com/matthysse-i-robbed-judah-far-better-devon--40814. Again that's Bradley's best win
3. Zab Judah KO'd Mabuza after he made Kendall Holt quit. Most consider Holt to be one of Tim's best wins.
Not to mention Maidana, Paulie, and even McClosky easily **** on old LW's like Campbell, Casamayor, and even a faded Witter.
