When scrolling through players on this site, you may see that under the players traits, it says "Clutch" and then either "Yes" or "No". You probably have wondered on what the trait means and does. Here is a breakdown...
• Quarterbacks who are clutch affect themselves and the entire offensive line. (Must be losing by 8 or fewer points or tied within last 2 minutes or OT)
• RB, WR, and TE affect only themselves. (Must be losing by 8 or fewer points or tied within last 2 minutes or OT)
• Kickers have boosted accuracy and power. (Must be losing by 3 or fewer points or tied within last 2 minutes or OT. Also, must be fourth down unless there are under 10 seconds left in the game)
• For defense, this trait only matters for DBs and LBs. The clutch trait will only affect the given player (not teammates). (Must be within a possession winning or losing in last 2 minutes or OT)
Ratings that are adjusted include:
• QB: Awareness, Carry, Play Action, Throw Accuracy, Throw On Run
• OL: MAJOR boost to Pass Block
• RB: Carry, Catching, Pass Block, Stamina
• WR: Catch In Traffic, Catching, Release, Route Running, Spectacular Catch, Stamina
• TE: Catch In Traffic, Catching, Pass Block, Release, Route Running, Spectacular Catch
• K: Kick Accuracy, Kick Power
• S: Awareness, Catch In Traffic, Catching, Hit Power, Play Recognition, Pursuit, Tackle
• CB: Awareness, Catch In Traffic, Catching, Hit Power, Man Coverage, Play Recognition, Pursuit, Tackle
• LB: Awareness, Catch In Traffic, Catching, Hit Power, Play Recognition, Pursuit, Tackle
Basically, the trait "Clutch" allows your players to get these boosts when needed most. This allows them to make better plays that may have not been made otherwise.
