Just found this thread . . . and I feel like I was ambushed. There is a lot to know about this game, but the info base is too much of a moving target. I thought I was getting it . . . but I missed one detail.
This explains why I was doing well my first month (old code), and then my win percentage dropped hard, along with my substitute QB stats. I became aware of the change, but had no idea why.
Playing more than one QB or using a substitute IS a valid philosophy, convoying IS an exploit.
The "fix" went too far. There is cold, and then there is stone cold dead. Time to dial it back.
