I'd pick him over Thurman, Maidana, Porter, Ali and maybe Spence at this stage Loses to Mayweather, Pacquiao, Brook and Khan
While being the better fighter, I have doubts as to if Bradley would be able to avoid trouble for 36 minutes against both Maidana and Porter. My guess is he would not, multiple times, and that it would spell trouble against those guys.
Sadam Ali could be a nice first mando defence later this year. Khan would be a decent fight as well. Apart from Spence, need to see more of him, most others on the list could beat Bradley at this point. Especially hard punchers like Thurman and Brook would probably stop him with a TKO/RTD.
