I imagine something like the apf 2k8 traits but dealing more with personality which would govern both the player's on and off the field behavior and influence on his teammates:
Firestarter: This player's energy is infectious. Whenever he makes a big play, it energizes and hypes up that side of the ball. Similar to 'Vocal Leader' he also rallies teammates on the sideline in critical game situations. He's a more mature version of the Loose Cannon player.
Mentor: This player tends to share his knowledge with younger, less experienced players at his position which is especially beneficial to incoming rookies. He is drawn to Loose Cannon players and helps to rein them in.
Vocal Leader: This player has the respect of everyone on the team and hold players accountable on his side of ball and in his position group. He will also approach the head coach as the spokesman for the lockeroom regarding the player's concerns.
Loose Cannon: This player is very emotional and lacks discipline. On the field he will often gamble and abandon his assignment to make a big play. He does a lot of trash-talking and tries to intimidate opponents. He will sometime question your coaching decisions in the media.
Lunch Pail: This player works exceptionally hard in practice and in the film room. He will often take extra reps after practice is over. Good to have one of these at a position that is relatively young as this player's work ethic rubs off on those around him. He also as the ability to play with injuries that might sideline most players.
These are just a few I could come up with for now. Im sure you guys could think of more and how they intertwine with the other traits/personality types.
