OK I was a little quick publishing those stats. Those are the percentage of runs on each down relative to the other downs, not relative to passes. Sorry about that.

Here are the 5-yr. run vs. pass rates in the 4th Q with a lead (all downs combined).

NE - 58%
GB - 63%
League - 65%

Belli is 5% more likely than McCarthy to pass with a lead in the 4th. McCarthy is 2% more likely than the league average. Both are very successful closing games.
