When Hoomanawanui caught a 14-yard pass in the third quarter of the Ravens' 35-31 AFC divisional-round playoff loss after he lined up at left tackle, Harbaugh erupted.
"Maybe those guys got to study the rule book and figure it out," Patriots quarterback Tom Brady said. "We obviously knew what we were doing, and we made some pretty important plays. It was a real good weapon for us. Maybe we'll have something in store next week. I don't know what's deceiving about that. [The Ravens] should figure it out."
Harbaugh wanted the Ravens to have enough time to identify who the eligible receivers were before the snap so that they could adjust their coverage schemes.
"It's a substitution type of a trick type of thing," Harbaugh said. "So they don't give you the opportunity. They don't give you a chance to make the proper substitutions and things like that. It's not something that anybody's ever done before. The league will look at that type of thing, and I'm sure that they'll make some adjustments and things like that.
"We wanted an opportunity to be able to ID who the eligible players were, because what they were doing was, they would announce the eligible player, and then time was taken, and they would go over and snap the ball before we even had a chance to figure out who was lined up where. And that was the deception part of it. That was clearly deception."
