Five keys to the game

FIVE KEYS TO THE GAME

Can Ponder repeat?

It'd be asking a bit much for Christian Ponder to repeat his brilliance from last Sunday's win in such a pressure-packed road playoff game. Ponder and the Vikings haven't trailed much at all since leaving Lambeau Field on Dec. 2. This time, they'll be stuck playing from behind. Can they respond?

Where's Antoine at?

Now finishing his 14th season, Antoine Winfield has played six career playoff games. Whether he can add a seventh to that log will be a big deal. Still dealing with significant pain and swelling in his fractured right hand, Winfield will wear a sturdier soft cast this week and his availability will be a major X-factor in the Vikings' attempts of slowing Green Bay's passing attack. After Winfield left last week's game late in the second quarter, the Packers piled up 318 passing yards and 27 points on their final six possessions.

Walsh finding his range

One of the most critical moments Saturday will come during pre-game warm-ups when Vikings rookie kicker Blair Walsh tests his range in the cold winter air of Lambeau Field. Walsh was 10-for-10 from 50 yards or longer during the regular season. But only two of those bombs came outdoors – a 51-yarder in Indianapolis in Week 2 and a 55-yarder at Seattle in Week 9. Before Saturday's game, Walsh will have to test not only his range but his cleats for footing and the direction of the winds. It'll be a key moment for the Vikings in determining their scoring range.

At the end of 2011, the Vikings were convinced they needed to find ways to better take advantage of Everson Griffen's athleticism and playmaking ability. A Mankato experiment at linebacker bombed. But the Vikings then found plenty of opportunity to use Griffen as both a defensive end and tackle. Last week he delivered three big sacks, the latest signs, Jared Allen says, of Griffen's increased understanding of the game. "That," Allen said, "is what separates good players from average players and great players from good players."
