In a recent ESPN broadcast, former New York Yankees slugger and current baseball analyst, Alex Rodriguez, declared that New England Patriots quarterback Tom Brady’s plan is to play in the NFL until he’s 50 years old. While doing analyst work for the Boston Red Sox and Seattle Mariners game at T-Mobile Park in March, Rodriguez said that two people told him that they want to play until they’re 50 years old. They were Brady and Ichiro Suzuki, who retired recently, at age 45.

While many people did not take Rodriguez’s pronouncement seriously, one person close to Brady believes that the quarterback can play at a high level until he’s 50 years old.

According to Alex Guerrero, Brady’s close friend, business partner, and training guru, the quarterback has plenty of gas left in the tank.

Guerrero calls Brady his ‘best friend’

Deadspin published an excerpt from the book “No One Man Should Have All That Power: How Rasputins Manipulate the World," by Amos Barshad, where Guerrero detailed his relationship with the 41-year-old Brady, whom he called his “best friend.”

When asked if Brady can still play at age 45, Guerrero replied: “Absolutely,” saying he knows how Tom feels every day. After every game, Guerrero said Brady told him that he doesn’t have any soreness and ready to play again. “Do I think Tom can play to a high level at forty-five? Absolutely,” Guerrero said.

When Barshad asked Guerrero if Brady could play until he’s 50 years old, the trainer replied “I mean, why not? I’ve never put limits on myself, and I’ve never put limits on any of my clients.” Guerrero explained that the human brain doesn’t understand the concept of time and age. “How would your brain know you’re whatever age you are?

I always tell Tom, we’re not gonna tell our body what we wanna do. We’re gonna tell our body what we want it to do,” he explained.

Last season, Brady completed 375-of-570 passes for 4,355 yards and 29 touchdowns and 11 interceptions. However, the veteran quarterback came up short of earning performance bonuses after he failed to make it to the top 5 in several categories.

However, he still led the Patriots to their sixth Super Bowl trophy with a masterful 13-3 win over the Los Angeles Rams.

Guerrero a controversial figure

Brady is known to have a close relationship with Guerrero, who also has several Patriots players as clients. The trainer is a controversial figure since his training methods are always at odds with the Patriots. The relationship between Brady and head coach Bill Belichick was almost strained after the latter stripped the trainer of some team privileges.

There were reports that Belichick prevented Guerrero from boarding team flights and prohibited him from staying on the sideline during games. In addition, Belichick stopped Guerrero from treating other players, aside from Brady, at his exclusive office in Gillette Stadium. Guerrero and Belichick both denied the rumors.
