To say Washington Redskins quarterback Robert Griffin III has a chip on his shoulder entering his third season in the NFL would be an understatement based on his recent Twitter proclamation against his detractors.

The Redskins third-year quarterback took to Twitter and had a very special message for those that doubt him.

"They doubted in high school. They doubted a turnaround @Baylor. They doubted a Heisman was possible. Keep doubting. It's nothing New," RG3 wrote.

Griffin's Wednesday night rant began when he was criticized for sliding awkwardly when he ran the ball during Monday night's 24-23 preseason Week 2 victory over the Cleveland Browns.

"Just want y'all to know I will keep working on getting down and not take those bigs hits. Got it right the third time," he tweeted.

Just one day after the tweet marinated, Griffin didn't care to elaborate any further.

"I said what I needed to say, there's no need to look into it," Griffin said Thursday via ESPN. "It's right there on Facebook, it's on Instagram, it's on Twitter. It is what I believe and what our household deems necessary to go out every day and be successful. That's all I've got to say."

Griffin, who is far from the only NFL quarterback or NFL player on the social media site, believes that sometimes things get overblown on Twitter.

"To each his own," he said. "There's 1.1 million people on Twitter that want to hear what quarterbacks and guys have to say. It's not that we tweet all the time, but anytime we tweet something, it gets blown up."

Griffin also said he uses Twitter as an escape from the daily grind.

"We spend a lot of our day focused on football so when we get a chance to unwind, whether it's watching reality TV or being on Twitter for five minutes a day, that's not subtracting from what we do on the field and in the film room," Griffin said. "A lot of guys have to find ways to unwind and relax for 10 to 20 minutes out of the day and that's the way we do it."

Griffin, 24, burst on the scene as a rookie in 2012 and went 258-for-393 (65.6 percent) for 3,200 yards with 20 touchdowns and five interceptions and ran the ball 120 times for 815 yards while reaching the end zone seven times as Washington won the NFC East for the first time since 1999.

Griffin was derailed by a knee injury during that season that he re-injured during the 24-14 wild-card round loss to the Seattle Seahawks.

The quarterback recovered in time to take his place under center in his second year, but didn't quite have the same dynamic season. Griffin went 274-for-456 (60.1 percent) for 3,203 yards with 16 scores and 12 picks in 2014 and rushed for just 489 yards on 86 carries without a single rushing touchdown.

Griffin has received some criticism about his rushing game, but he's taken it in stride.

After all, the young quarterback relishes proving doubters wrong.
