Navy's triple option offense is hard to defend.
There are so many different ways a play can go and with few college programs running that type of offense teams have very little time and examples to prepare for it.
But Notre Dame defensive tackle Ethan Johnson said nose tackle Ian Williams has given him a tip to help anticipate which way a play is going by watching the offensive linemen.
"If you watch the film, you see a lot of the O-linemen start to kind of move before the ball is snapped," Johnson said. "They anticipate the count, and since kind of all of them do it, they never get a false start call. It's interesting.
"Ian said that (former Notre Dame defensive) Trevor Laws used to anticipate (where Navy would run to) because they would lean where going before each play. It kind of gives you a little bit of an edge. You can see kind of where they are leaning to."
Johnson, who played a few snaps against Navy last year as a pass rusher, said he hasn't seen it live but he has picked up on the Midshipmen's lean on film.
Johnson said since the Navy linemen look like they are shifting their weight and not jerking that is why a false start is not called.
