NFL Predictions: Which Quarterbacks Are Under the Most Pressure?

The 2011 NFL season has only had one game, but there are a handful of quarterbacks already feeling the pressure to perform.

Football fans are a fickle bunch, and one bad week might be enough to call for the backup. While some of these players might have job security for now, each one is already feeling the heat. They will need to perform well to silence the critics, both inside their organization and out.

Some quarterbacks on this list have been playing poorly for years, while others simply have a reserve just waiting to take their job.

With a poor performance this week, these players will be looking over their shoulders and hoping they do not get replaced.
