It's certainly possible that a player can change once he gets a lucrative contract, like the one Redskins quarterback Trent Williams received this offseason when the team franchise tagged him for 2016.

But after a few months of Cousins adjusting to the realization that he'll be receiving a hefty contract this year, and potentially for the foreseeable future, it appears he has been immune to any kind of transformation.
At least, according to one of his teammates.
"He's the same guy – joking around at lunch today – that we've had in his first four years her," linebacker Ryan Kerrigan said Monday on a conference call. "If anything, any change that comes from him I think will be a positive one. I'm excited to see him continue to grow and continue to lead this team like he did last year."
That might mean becoming even more vocal now that Cousins is assured the starting quarterback position. After losing veteran leaders such as Dashon Goldson, Terrance Knighton and Jason Hatcher, the void, Kerrigan believes, will be replaced by teammates ready to grab their job by the throat this season.
"I'd say probably Kirk [Cousins] would be a good candidate to fill those roles," Kerrigan said. "He's a guy who does things the right way. He leads by example but also he can speak really well, so I imagine he'll fill a lot of that void from an offensive perspective. I think a guy like DeAngelo Hall has always been a vocal leader with us, so I imagine he'll continue to expand his leadership role as well."
