Tariq,
I like the work you are doing here and I know this game is frustrating. I wonder if we are going about it the wrong way.....

The actual number of "big plays" per game is insanely low in the NFL. It makes me think that a higher threshold might be more appropriate. It might even help "solve" some of these coverage issues. Now, we'd practically have to re-invent the wheel slider-wise to make it work...but I'm not sure we are going to do much better than what we are with these sliders until we go back to basics.
