NFL Playoffs, week 2

So I went 2-2 last week, both picking winners and against the spread. Before we move onto this weekend's games, a review of previous years:
2009: 7-4 picking winner, 6-4-1 against the spread
2008: 6-5, 3-7-1
2007: 7-4, 6-5
2006: 5-6, 5-6
2005: 8-3, 7-4
2004: 5-6, 2-8-1
2003: 8-3, 4-7
Totals: 46-31 picking winners (60%), 33-41-3 against the spread (45%).
Cardinals at Saints, Saints favored by 6.5. I'm struggling with this one. Not 100% sold on the Cards, but that offense was sick last week. Was 100% sold on the Saints a few weeks ago, but they really sputtered down the stretch. I guess I'll say Saints 35-28, but this is a stay-away game for sure if you're putting any real money on it.
Ravens at Colts, Colts favored by 6.5. I think this actually a fairly straight forward one. The Colts were great in the regular season, but every time they have a bye and rest their starters in the last week of the season (or two in this case), they lose their first (and thus only) playoff game. The Ravens just need Flacco to improve to decent from last week's poor performance and they're good. Ravens 27, Colts 20.
Cowboys at Vikings, Vikings favored by 3. The Vikings played a very easy schedule, and tailed off at the end. And I'm still a Favre doubter. They have a chance with AP, but they have one of the few coaches who Wade Phillips can outsmart, and Dallas is playing very well. Cowboys 31, Vikings 20.
Jets at Chargers, Chargers favored by 8. The Jets definitely have a chance, with their stout D and running game. However, I'd be surprised if Sanchez can do it again on the road in the playoffs, especially if he's playing from behind. The Chargers have too many weapons, and are just too plain good. Chargers 31, Jets 17.
