Aaron Rodgers finally ended his weeks of uncertainty on Thursday by agreeing to join the Pittsburgh Steelers. And he already has an ultimatum even before officially signing his contract: win it all, or else.Upon seeing the development, former quarterback and analyst Robert Griffin III warned the Super Bowl champion and multiple-time MVP that anything less than a contention for the Lombardi Trophy would be considered a failure for his new team's fans."Every move the Pittsburgh Steelers have made this offseason was with the belief that they are ready to win it all now," he said. "They are all in on Aaron Rodgers being the QB who can make enough plays to get them over the hump and not make the plays to hurt them."If he doesn’t and the Steelers don’t make a deep playoff run, the demand for changes will be deafening."Robert Griffin III @RGIIIThe Pittsburgh Steelers have to be Super Bowl Contenders with Aaron Rodgers at QB.For Cameron Heyward (36) and TJ Watt (30) this is likely their last chance to win it all in a Steelers uniform.They traded for DK Metcalf to pair him with ARod, Freiermuth, Austin III and a duo of Jaylen Warren and Kaleb Johnson at RB.They brought in Super Bowl Champion Darius Slay to pair with Joey Porter Jr and Minkah Fitzpatrick.They play in the toughest division in football in the AFC North facing off against Lamar Jackson and Joe Burrow 2-3 times a year to get to the promised land.Every move the Pittsburgh Steelers have made this offseason was with the belief that they are ready to win it all now.

Speaking on SportsCenter on Thursday, he derided it as a "worst-case scenario" that "keeps the team mired in mediocrity," a state that arguably began when Ben Roethlisberger retired after 2021."Have they gotten better in the quarterback room? Absolutely," Clark said. "Will they contend for that championship that Pittsburgh Steelers people and fans and organization think is the standard? No, they won’t."The decision comes at a very crucial time for the Steelers, as they will be holding their mandatory minicamp next week from June 10 to 12.

Lazard is a perfect complement because when Lazard is with Rodgers, he plays really well; when he is not with Rodgers, he does not play very well,” Florio said (from 07:41).The team's preseason begins on August 9 against the Jacksonville Jaguars. Their regular season begins on September 7 at the Jets.
