I'm not 100% Bradley will beat Khan or anything like that. I simply think he does pose some stylistic difficulties that might ultimately be more challenging than Judah's power and handspeed alone. It was one of my most anticipated fights this year, and while Judah is the most acceptable alternate opponent, I am disappointed that it's not taking place. That being said, I also don't really think Bradley's ducking here and that pretty much no one would take a fight like this one week before they're about to go on the market as an already sought-after free agent (though he does look like a jackass for making constant call-outs and letting Shaw and Golden Boy essentially dictate that the story would be framed with him in the worst light possible).
I dont think bradley could KO khan but judah can. If khans level drops at all then the experienced judah could take advantage and khan is very sloppy at times, fast but sloppy. Its a good replacement fight for chicken bradley.
