Bradley is 50-50 IMO. Disregarding punchers chances, I'd favour Khan against the rest of 140lbs, and even though he hasn't progressed to 147lbs yet, I'd give him a very good chance against most.
Bradley's lack of power would cost him against Khan and Ortiz and Berto are too easily hit. I'd favour Khan to win all of those... Roach has had plenty of practice coming up with game plans to take out fighters with that style. Kell Brook in a year or two could be a good fight, but he'd need to work on his head movement. He's a powerful, accurate puncher and that could cause Khan issues. Khan doesn't jump in as much as he used to, but he's still got that tendency. Someone with power who can counter punch will always cause him problems.
berto and mosley favourite @ 147 probably 4/5 If Paul Williams or Miguel Cotto came down to 147 they would be clear favourites like 1/2 bradley and ortiz probably very close like around evens all the others khan favourite pac and mayweather probably start at 1/8
