The quarterback led the team on an 80-yard drive in the final minute of the game before rushing for a game-winning touchdown against the NFC East side.
Simms, who now works as a commentator, told Inside the NFL: "It tells me he is truly the man there. That he took it upon himself to read a situation and take advantage of it.
"They got a quarterback because they want to fire it down the field. They want him in the shotgun. So who better than Matthew Stafford in that situation? In my eyes, two quarterbacks in the NFL can make that throw. One of them is Aaron Rodgers. The other is Matthew Stafford.
"That was a phenomenal throw. When he completed that, I bet you the defensive back went, 'Are you kidding me'? He was on the right hash to the left sideline."
The Lions, who are on their bye week, face the Chicago Bears next weekend.
