Well Oakland in real life only has 7 through 14 games so .5 per game. Seattle only has 10 through 14 games.
What is the league leader at in your franchise?
I usually see 1 to 2 per game just controlling the DT. Some games I see zero. I would wait and see what you end the season at, because I definitely see them at a frequency that seems legit.
How many fumbles have you forced and recovered?
