Longtime Steelers' reporter Ron Cook has had enough of Antonio Brown's antics.

Cook, a longtime writer for the Pittsburgh Post-Gazette, was extremely critical of Pittsburgh's All-Pro receiver in a recent story where Cook calls for Brown to "grow up" in light of Brown's fines for uniform violations this season as well as his sometimes negative attitude towards his quarterbacks.

"A lot of what the narcissistic Brown does is just silly," Cook wrote. "His battles with the NFL police over the designs on his cleats are ridiculous. What? He can’t be like his teammates and follow the rules? And, to think, he says he doesn’t like to call attention to himself. Please. He’s the ultimate look-at-me athlete in a sports world full of them.

"Brown’s excessive celebration penalties, blatant pouting when the football doesn’t come to him enough and the way he has shown up his quarterbacks on the field, including Ben Roethlisberger, are much more hurtful to the team and unbecoming of a terrific player.Brown also has taken indirect shots at offensive coordinator Todd Haley. Asked about his lack of production in the loss Sunday to the Miami Dolphins — four catches for 39 yards — Brown said, dismissively, "'I don’t call the plays. I just run the plays,' ".

Cook was especially critical of Brown's perceived lack of hustle late in Pittsburgh's Week 6 loss to the Dolphins.

"Late in the game, with the clock running, Brown jogged back to the line of scrimmage long after the rest of his teammates were ready to run another play in their 2-minute offense," Cook wrote. "That was way over the line. It would have taken a miracle for the Steelers to tie or win the game at that point, but so what? Brown’s lack of hustle was disrespectful to (Mike) Tomlin and the other coaches and players.

"Don’t think that everyone on the field and in the organization didn’t see it."

Cook also didn't give Tomlin a pass for Brown's actions, writing that the Steelers coach needs to straighten out his receiver.

"Shame on Tomlin if he didn’t demand a meeting with Brown Monday morning (after the loss in Miami) to give him the business," he wrote. "Shame on him if he didn’t call Brown out in front of the other players during their Monday meeting. Tomlin has allowed Brown to get away with all of it because Brown is incredibly gifted and the Steelers’ hardest worker. But, in the process, Tomlin has created a monster of sorts."

While he not questioning his ability or work ethic, Cook obviously has an issue with how Brown has conducted himself both on and off the field. He obviously doesn't think it's a good look for Brown, Tomlin, and the Steelers' organization as a whole, who hope to get back to it's winning ways next week against the Ravens.
