Over the course of the 2012 regular season, the Patriots had two or more tight ends on the field for almost an even 50 percent of their snaps. That is lower than expected and ties directly to injuries sustained by Rob Gronkowski and Aaron Hernandez. If those two tight ends were healthy over the duration of the season, the percentage probably would be closer to 75 percent, if not higher. The trickle-down effect of that is that the Patriots ran an almost even 50 percent of their 2012 regular-season snaps with three or more receivers on the field.
