I've seen JoN use many different fronts this season, but this is the first time I noticed the 3-4 NT one gapping. Most likely it's been going on all season, just didn't notice until now because Dorsey was flying into the backfield. He is clearly not two gapping in the plays below when the 49ers are in base 3-4.
All these plays are from the 1st quarter.
3-4 Under (NT shifted to the strongside, weakside DE inside of the Tackle): Dorsey playing 1tech. One gapping into the strongside A gap.
This looks like a 4-3 Over with Eli having his hand in the dirt. Again, Dorsey as a one gapping 1tech. Traditional 4-3 fronts are one gapping so this play isn't odd in any way.
49ers in a nickel front here so it's not odd that Dorsey (1tech) is one gapping. Just wanted to show more of Dorsey working that MIA center.
3-4 Under: Dorsey one gapping as a 1tech, busting into the backfield.
Just occurred to me that this is MIA's backup center. That kinda puts a damper on things. Would have meant more if that was Pouncey at center.
