Warrior General Games

I have kicker: http://glb2.warriorgeneral.com/game/player/100942
on that team: http://glb2.warriorgeneral.com/game/roster/1092

I choose the trait "easy going" to get his chemistry up fast. He has a medium contract. All players with medium contracts gained 4-6 points in chemistry from the first day. My kicker gained 4 as well. Is there a dice roll for chemistry gain as well and I was unlucky with my player, or is "easy going" not working?

I took easy going on mine too, for the heart increase. On a high salary got 8.

Actually I have some on a high contract that only got 6...some 7's and some 8's. Heck my S* HB only got 5 on a high contract...
