Shawn Porter couldn’t care less about how heavily favored Errol Spence Jr. is to beat him.

The WBC welterweight champion is certain that he is the best opponent Spence has agreed to fight. Now that he has completed a grueling training camp, the prideful Porter can’t wait to prove it Saturday night.

That’s when they’ll square off in a welterweight title unification fight at Staples Center in Los Angeles.

“I’ve got nothing left to say to you guys other than that I’m looking forward to the 28th,” Porter said during a recent conference call. “I’m sure you guys are used to hearing that. But the thing you’re not used to hearing is the world is about to be shocked. Team Porter has done a fantastic job in getting prepared for Errol Spence. We aren’t overlooking anything that he can do in the ring, but we definitely feel that we are the superior athlete, the superior fighter and we are all looking forward to displaying that and shocking the world on the 28th.”

A Porter win would be surprising, if not shocking.

Las Vegas’ Porter (30-2-1, 17 KOs) defeated Philadelphia’s Danny Garcia (35-2, 21 KOs) by 12-round unanimous decision to win the then-unclaimed WBC 147-pound title a year ago at Barclays Center in Brooklyn. That was the most noteworthy win of Porter’s 11-year pro career, but the unbeaten Spence (25-0, 21 KOs) might be boxing’s best welterweight.

The DeSoto, Texas, native is taller and a harder puncher than Porter. He has knocked out 84 percent of his opponents, whereas Porter has won only 52 percent of his professional fights inside the distance.

Kell Brook, one of the two opponents that has beaten Porter, is among the powerful southpaw’s knockout victims.

Brook beat Porter by 12-round majority decision to win the IBF 147-pound championship from him five years ago in Carson, California. Spence took that title from Brook in May 2017, when he knocked down Brook twice and stopped him in the 11th round in Sheffield, England, Brook’s hometown.

Most handicappers have established Spence as a 10-1 favorite in their FOX Sports Pay-Per-View main event.
