After Sunday's win, Cook could be seen smiling from ear-to-ear inside the Packers' locker room, as he placed a NFC North division champions cap on his head, the first piece of playoff memorabilia he's ever acquired in 117 career regular-season games.

"When they passed out those championship hats, I don't think I've seen anybody smile to put it on his head more than Jared Cook," Packers Head Coach Mike McCarthy said. "That's the beauty of this because you have players here that have been in that position, they're thankful, they're appreciative, but they're also looking forward.

"But for the rookies, first-year players and the guys who have not, it's a big deal and it should be. It's a big deal to win a division championship in this league. To me, that's just another component of the energy and confidence you want a part of your football team."

Cook said on Monday that his experience is a little different from the rest of the locker room. Other than a smattering of rookies, he's the only veteran who's never been to the playoffs before.

At the same time, the task is far from over for Cook and the Packers. Another challenge awaits them this Sunday when the No. 4 seed Packers host the No. 5 New York Giants at Lambeau Field.
