The final weeks of the NFL regular season will make or break several teams, with one magic moment or bad blunder changing the outcome of a squad's entire 2012 campaign. Momentum is particularly important during the last few weeks of the season, as teams with deep playoff aspirations need to finish on the upswing heading into the postseason.
