Sorry but that is an incredible biased statement against Cousins as nothing you say is accurate in the least and it's only because of the Dak comparison that you are making such statements.
Vernon Davis in 2017 about Kirk Cousins:
"So here’s veteran tight end Vernon Davis, rhapsodizing about the merits of Cousins during a Monday appearance on ESPN 980.
“He’s a young guy in the league, and I think sometimes we forget about that, that he’s only been a starter for two years,” Davis said. “And with that being said, he’s doing all the right things. He’s doing all the right things. Guys in the locker room love him. They think he’s spectacular. I do, as well, because of what he does. He minimizes himself in the locker room; in practice and in games he stands out like a sore thumb.
“And that’s what great quarterbacks do. That’s what they do. I watch those things, and he’s putting his teammates first. He’s putting his teammates first. So that’s first and foremost. He’s growing, he’s evolving, so I’m excited about his career and excited about his future. I think he’s going to be a wonderful quarterback in this league.”
Dede Westbrook yesterday about Kirk Cousins:
"Soon after he signed with the Minnesota Vikings last weekend, Dede Westbrook looked at his phone and got a surprise. The wide receiver had received a text message from quarterback Kirk Cousins, welcoming him to the team.
“I thought it was crazy because obviously Kirk has been in the league for a while. I’ve been watching him for a minute now,’’ Westbrook said after Wednesday’s first practice of training camp. “Obviously, for me to get that text message saying, ‘Hey, it’s Kirk Cousins,’ he’s excited to work with me, my heart kind of dropped. I’m excited to be out there with him too, building that chemistry.”
So while of course you will have players loving their QB and some saying they couldn't stand them, to make a blanket statement saying his teammates don't like him and he lacks leadership is just wrong.
