The Problem with Mark Ingram
No RB will excel in the empty backfield set, and we run it a lot. The Saints would rather have an extra TE and play the matchup game than to pound the defense and control the clock.
I prefer the "I" backfield, with the TB 5-7 yards deep. Ingram is a terror in the deep I set. He was born to run from the I.
Not many teams use the I, because they also like to use 2 TE's. But, you can use a TE in the I as the FB, as we did with Dave Thomas. It worked great.
The I is very, very versatile, and the defense never knows what you are going to do. The only deception you can use out of the empty set is a jet sweep.
