Senses Pressure - there are 5 types of this trait, and relates to how the QB reacts to pressure, and can have an impact on certain stats. These are still in active even when you are controlling the QB.
Trigger Happy QB's will try and get the ball out as quickly as possible when under pressure, even when the receiver is not open or the conditions are not ideal. These QB's don't want to be hit, so their goal is to get rid of the ball. Stats that are improved are how quickly they get the ball out, but decreases stats such as their accuracy.
Paranoid QB's are always under the impression that they are about to be hit, and are more likely to make inaccurate or poor passes. When a QB isn't under pressure, they are able to make better passes, however paranoid QB's are essentially "always under pressure". One benefit of this is they are usually bracing the ball at all times and are ready for the sack.
Oblivious QB's are unaware of an impending sack. They will continue to perform as if their is no pressure, which can enhance certain passing stats, however they will not get rid of the ball quickly nor brace that well when they are about to be or are hit/tackled. This trait often leads to more tipped passes and more fumbles.
Ideal QB's will have a combination of the above traits. They will feature the oblivious boosts when they are not under pressure and will feature the paranoid traits when they are under pressure and will feature the increase release seen in trigger happy, but maintain their accuracy. They will react quicker to pressure, brace when they need to, and their passing boosts will change quicker depending upon the situation. This is the trait you want.
Average QB's will feature a a combination of the above traits, however they will be slower to react to the pressure and take longer to sense the pressure.
