Pressure is a fact of life when you play in the NFL.
The ability to perform under this enormous mental strain separates the All-Pros from the wannabes.
When a team puts a player in a situation where if they falter, the season crumbles, it makes the pressure even more intense.
With that in mind, here's a look at eight players who are facing that kind of stress as training camp begins.
All of them are being counted on to step up and be a catalyst for their team's success.
Seven are on the offensive side of the ball and three of the eight are rookies. Feel free to comment with your own list or differences of opinion.
