"Player Traits" need to be updated during the season.

Just like ratings. 

For example, a LB who doesn't come into the season with the "big hitter" traits yet shows to be just that...should have his trait updated. 

A QB with a certains "release" but shows he's changed it in the off-season...(I.E Trey Lance) needs to have it updated. 

A RB who may have "braces for most hits" but runs harder this year. Same difference. 

Same for receivers and their catching traits. 

Bottom line, traits need attention.
