I'll take Provodnikov in any fire-fight at 140lbs.

He beats all them except maye Peterson. He can stick and move

Belts mean sh_t anyway. He's still going to get the big fights and Danny Garcia is still the man at 140. Ruslan will still get a chance to get his gloves on JMM or Rios.

JMM KO's Ruslan at 140.

On your list I would only pick Ruslan to beat Molina

That is Provodnikov's world (All-out brawling) Just keep him away from technically skilled boxer's. IMHO: Roach (The Great) should have picked up on this during his training and scouting. And also should have groomed a plan specifically to counter that fault.
