I sense he's taking a mild jab at Romo and Mahomes.
Rodgers and Russell have rings. Romo's reputation, albeit an exaggerated one, is he'd take chances - sometimes they looked great, other times...
No, that's not it. He's talking about the ability to make plays out of nothing and keeping his eyes downfield. Mahomes doesn't look to run, just like Romo didn't when he was young. He's looking to buy time to make plays, and he's really elusive in the pocket like Romo.
Mahomes has a Rodgers-like arm. He throws with such ease.
He has Wilson-like presence and ability to run.
He has Romo's ability to feel pressure with his eyes still downfield, escape it, find his feet, and deliver the ball on target again and again from different arm angles.
