interesting, haven't verified it....but,
The "right time" to get hot is in the playoffs. Consider...
2009 SB Champs: New Orleans. Last 3 games: 0-3, two of those were at home. That included a loss at home to 3-13 Tampa Bay.
2010 SB Champs: Green Bay. Last 5 games: 2-3. That included a 7-3 loss to 6-10 Detroit.
2011 SB Champs: NY Giants. Last 8 games: 3-5. That included a two-TD loss to 5-11 Washington.
2012 SB Champs: Baltimore. Last 5 games: 1-4.
2013 SB Champs: Seattle. Last 4 games: 2-2.
2014 SB Champs: New England. Last 5 games: 3-2
