"In our philosophy, the tight end is a needed component because of the physical nature with which you want to play football," Harbaugh said.
His words became measured.
"The tight end. A fullback. Needed. Without those two positions, you tend more to be a finesse type of team."
Now he was rolling again.
"Especially if you can get a fullback, a man who lives a spartan life, who goes to bed and dreams about physical confrontation and getting from Point A to Point B to go hit somebody," Harbaugh said. "If you have that kind of face as your identity for your team, then you can play the kind of football that we are talking about."
