I use a percentage based system to shade the results such that completion percentages are more accurate and the possibility of interceptions is increased.
So, when I find an open receiver and stop the board, I roll two 6-sided dice of different colors (red, white).
If they come up the following:
R-W
1-2
1-3
2-1
2-2
5-6
6-5
... the pass is incomplete and the play is over. If it comes up snake eyes, the pass is intercepted by the nearest unengaged defender and can be run back. If it comes up 6-6, the pass is intercepted and the play is over.
Any other dice roll, then I throw the pass and proceed normally.
Between that, and the percentage of TTQB passes I hit, I've been very happy with the completion percentages I've been getting in my games.
