Biggest coaching fears for Denver

In my 30-plus years as a player and coach, I was fortunate enough to have made the NFL playoffs many times. There is simply a different energy in the postseason, because of the finality of it: If you lose, you're going home. There is no tomorrow.

If you've been to the postseason before as a team, you recognize that. And a team like the Denver Broncos that was a Super Bowl favorite and fell short last season understands it even more. They know what to expect when they take the field against the San Diego Chargers on Sunday. There is certainly increased pressure on Denver to reach the Super Bowl, and against a Chargers team that has now won five straight games, there is much for John Fox and his staff to be concerned about.
