The Indianapolis Colts and Seattle Seahawks meet in a battle with playoff implications Sunday. Kickoff from Seattle, Washington, is 4:25 p.m. ET

The Seahawks made key roster moves before the Colts game, activating Jalen Sundell, Eric Saubert and Rylie Mills while placing rookie TE Elijah Arroyo on IR.

Operationally, the one thing that could sink this team's Super Bowl aspirations is a lack of ball security. According to Vinnie Iyer at The Sporting News, turnovers are Seattle's one potentially fatal playoff flaw.

The Packers are coming off a last-second win over the Chicago Bears, wh ich thrust them back atop the NFC North and the No. 2 seed in the NFC. They've garnered tons of momentum with that victory, which, if you've been paying attention to the Packers this season, is exactly the time they give it all back with a loss.

The fourth-year Seattle Seahawks cornerback was penalized over the same transgression twice this season, and that’s bad news — for him.

According to Tom Pelissero at NFL.com, the Seahawks lead the league in EPA/play defensively since the Week 8 bye, and they rank eighth offensively.
