Seattle Seahawks cornerback Richard Sherman is not afraid to express his opinion and his recent social media post got sports fans and other athletes to join in the discussion.

Dale Earnhardt Jr., Marc Methot, and Rickie Fowler were a few of the athletes who either agreed or disagreed with Sherman, NFL.com reported.

On Friday, June 12, Sherman asked the 12s, or the Seahawks loyal fans, to support his statement regarding the intensity of mental preparation a football player must engage in every game, compared to other athletes.

Dale Earnhardt Jr., a successful racecar driver, responded with an argument saying even racecar drivers like him should be prepared.

A professional golf player frankly told the 27-year-old cornerback that it is not a good idea.

Rickie Fowler, another golf player simply asked the California-born athlete to include his favored sport in the list.

Marc Methot, a professional hockey player, on the other hand, said that any athlete who is serious about his/her craft should be mentally prepared, to which Sherman agreed.

This is not the first time Sherman has engaged in a debate with another athlete. Although some of the opinions above were still at a very friendly level and less controversial, the exchange between the Stanford University graduate and the New York Jets' cornerback Antonio Cromartie, who criticized him two weeks ago, surely heated up various sports website's pages.

For the Jets' CB, the "Best Cornerback" title should be given to Darelle Revis because he follows the opponent's top receiver in the game, unlike Sherman who is "the only defensive back who hasn't."

"If you wanna label yourself as the number one, the best cornerback in the NFL, follow the best guy on every single team," Cromartie told Willie Colon of SiriusXM NFL Radio on June 2.

Sherman fired back at Cromartie, saying his statement was "unfortunate."

"Great players stay on their side and do what they're supposed to do," Sherman said, as quoted by NFL.com.
