'Bud', 34, will defend his WBO welterweight title against the Ohio native in Las Vegas next month on November 20.
The former two-time champ's chances of upsetting the pound-for-pound king have been written off by many, but Bradley insists it won't be a one-sided affair.
The former 147lbs king told FightHype.com: “When you’re fighting a guy like Terence ‘Bud’ Crawford, there’s not one thing that you can say that’s how you get over the hump.
"I think Shawn Porter, mentally, is one of the toughest guys.
"His mentality, I love it, he reminds me of mine — he just wants to fight the best in the world — so I respect that and I respect him.
“Crawford, he gets a chance to show if he’s special, like truly, truly special.
"Shawn Porter’s given everybody in the division hell — everybody. He either lose by split decision, close when he fought against Errol Spence.
"So this is a measuring stick, I think, that Crawford needs. We need to see what he can do against a guy like Shawn Porter. But I like the fight a lot. I think it’s a 50/50 fight."
Fan favourite Porter hasn't fought since his solid performance against former IBO welterweight champ Sebastian Formella in August of last year.
And Bradley reckons the ex-two-time-champ will give his former sparring partner a good run for his money if he fights the way he did against the German.
He added: “Damn right it’s a 50/50 fight.
"This is Shawn Porter we’re talking about, with a granite chin, a guy that’s cerebral, a guy that’s knows how to think inside the ring.
"He can change rhythms off and on. Terence Crawford is a rhythm type of fighter. Once he gets going he starts tapping on you, tapping you, tapping you — it’s almost similar to [Emanuel] Navarrette — once he starts tapping you, getting his jab going, then the combinations are flying.
"And I understand that so the fact that Shawn Porter, I know he knows how to change rhythms, he knows how to make adjustments inside the ring, he can box you at times, he can swarm you at times.
“One of the areas maybe he needs to be careful with is his lunging, because Terence Crawford has the craziest reaction time when it comes to intercepting offense coming his way.
“Many people think he stops Shawn Porter, I want to see that. I don’t know, Shawn Porter’s a different beast.”News Now - Sport News
