By logging a 21-year career that included 56 fights, the piling up of 366 rounds and the glory of standing as a world lightweight titleholder from 2014-2018, Jorge Linares fully understands the demands of boxing.

So when he inspects the carnival ride that Ryan Garcia has brought to the lead-up of his 140-pound title shot at unbeaten champion Devin Haney on Saturday, Linares is beyond befuddled.

“You can see [the difference from when] in the past when Ryan Garcia was not a champion and was in his prime, [and then] you see the reality of where he is now … ,” Linares said as a special guest on Pro Box TV’s “Deep Waters.”

“It’s shit. It’s bad. It’s toxic.”

“Being on [social media], it’s more bad than good. If my daughter tried to be his fan, I’d tell her, ‘No way!’ What [Garcia] says, ‘I smoke marijuana,’ and all these [other] things.

“Why? Why? Where is your professionalism? Where is your professional team?”

Southern California’s Garcia (24-1, 20 KOs) confronts a seminal event Saturday night, one year after he and another popular fighter in his 20s, Gervonta “Tank” Davis, generated 1.2 million pay-per-view buys for their bout.

The credibility that Garcia brought to that bout as a fearsome and rapid puncher was diminished by him staying on his knee after Davis landed a vicious body shot during a decisive seventh-round barrage.

Now, the bizarre and constant stream of Instagram posts have accelerated his followers, but left the sport’s purists like Linares awed by the recklessness.

“You can see it in his eyes: He’s very confused,” Linares said.

“Deep Waters” analyst and former welterweight titleholder Paulie Malignaggi wonders if it’s a signal that Garcia’s love for boxing has decreased.

“We know how important it is to be dedicated fully,” Malignaggi told Linares. 

“For me, personally, once I stopped loving boxing, I stopped improving.

“Does Ryan Garcia just like being famous?”

Linares responded, “That’s a very important” suggestion.

Chris Algieri, the former 140-pound champion and a “Deep Waters” analyst, said Garcia had it coming when he repeatedly asked Haney on the top of the Empire State Building, “Where’s your mom, bitch?” before getting slapped in the face and sent backward by Haney.

Afterward, Garcia promoter Oscar De La Hoya congratulated Garcia for getting under Haney’s skin, suggesting Haney will now be overly aggressive and come forward Saturday night. When that happens, De La Hoya advised Garcia, throw a knockout punch. 

“If a guy says something about my mother, I punch him in the face. I don’t care how much money there is to lose,” Algieri said. “There’s a line. That’s not me as a fighter [talking]. That’s me as a man. You can’t talk about my mom. I think a lot of people would agree with that.”

Malignaggi, who’s been through intense trash-talking episodes in his career, including one with the X-rated Adrien Broner, said while he agrees you can “draw a line [from] a personal standpoint, I really don’t think there’s a line when it comes to [fight] promotion.

“Me and Broner, there was no line. Granted, you take your chances on saying those things. There can be consequences – shoves, pushes – but, of course, I’m one of those guys [committed to selling] the fight. There was nothing off limits.”

Algieri said as the fight nears, the promotion “did not sell it well” and “missed the mark.”

Malignaggi agreed that the attention on the fighters’ professional grudge match after splitting six amateur bouts, along with their respective ring talents and verbal talents were obscured by the attention on Garcia’s erratic behavior.

“You’re not bringing the bad blood,” Malignaggi said. “You’re just doing all kinds of weird stuff.”
