In the NFL, players are always admonished to "keep their head on a swivel."
This season, I have given that same warning each week to teams that come in as favored but could just as easily leave as losers.
Heading into Week 14, teams are worried more and more with their playoff seeding, and their opponents are interested in playing spoiler.
Last week, "Upset Alert" only went 1-2 in terms of wins and losses, but the New York Jets were certainly taken to the wire by the Arizona Cardinals and needed to turn to Greg McElroy just to save themselves from embarrassment. The New York Giants were caught off guard for my only "win" of the week, while the Jacksonville Jaguars let me down yet again by getting crushed in Buffalo.
Remember the guidelines for Upset Alert: "Underdogs" are determined by Vegas odds; putting a team on Upset Alert is not picking them to lose (it's just putting them on notice); potential Upset Alert teams are based on matchups, trends and team-specific scenarios.
So which teams should be worried in Week 14?
