I'm just going to carry this theory over to it's own thread from the Lions game day thread.
You rang? I'll research that shortly because I'm curious now too xD. And I'm sitting on this huge penalty DB that I've been itching to use for something other than consuming bits on the ol HDD.That was posted for your benefit. If you know where to get that info, I'll help.
Every penalty from 2009-2016.

The +14 data might be a little misleading because there's naturally going to be more 14+ point leads in the 2nd half and therefor more penalty opportunities. But teams with a 14 point lead are getting called more often than teams who are trailing by 14+ in the 2nd half, where the penalty opportunities are dead even. And it's WAY more against the road team. I think there might be some bias there. It's even worse when you consider how the road team doesn't lead by 14+ nearly as often as the home team does. What do you guys think? It seemed pretty bad against us at Detroit.
strikes me as the types of things that can be quantified and published... volume of calls against a team with a large lead, calls against visitors, etc.
