The problem I have, and I admit I don't fully understand what it means, but you can have a negative rating for play familiarity. In league 79 - it was my team that lost in the championship game. I obviously scouted that play in my game planning - but when I look at the play in question - it says my team has a -66% Offensive Familiarity. NEGATIVE 66%.
I don't understand how it could be a negative number. As I said, I honestly don't know what that means - but every other play I look at ranges from 0-100%.
Another problem is that the team I played the game prior was similar on defense by running only a handful of different plays. Between those 2 games, my team took 13 injuries. 4OL, a FB, a TE, and RB. The opposing teams had 3 and 1 injuries in those 2 games. That game plan can really grind up a team.
I think there has to be some level of overuse penalty to make up for the fact that there is no in-game adjustments possible. Especially when there can be negative number assigned to play familiarity (which evidently means on 28 pass attempts you can count on 9 incompletions, 10 sacks, 1 INT, and 2 fumbles.)
