NFL Playoffs 2015-16, Round 1

First a review of previous years:
2015: 8-3 picking winners, 4-7 against the spread
2014: 6-5, 4-5-2
2013: 4-6, 3-6-1
2012: 7-4, 5-6
2011: 7-4, 6-5
2010: 5-6, 4-7
2009: 7-4, 6-4-1
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: 83-59 picking winners (58.5%), 59-77-6 against the spread (43.4%). So maybe bad enough to use me as a negative indicator. Putting really little thought into it this time.

Kansas City Chiefs at Houston Texans, KC favored by 3. Chiefs 23-20 (call it 23.5-20 for spread purposes).
Pittsburgh Steelers at Cincinnati Bengals, Pittsburgh favored by 2.5. Bengals 24-20.
Seattle Seahawks at Minnesota Vikings, Seattle favored by 4. Seahawks 22-20.
Green Bay Packers at Washington Professional Football Team, Washington favored by 1.5. PFT 21-20.
