How they treated the center position with Garza and Kreutz is just one example of this in the NFL. The Jets have Mangold as their center, and their backup center was Slauson. Mangold is a very sturdy durable center, so they too played the odds that he would not get hurt and would have to move a guard into Slauson's spot if that happened. It is more unusual to carry a dedicated backup center like the Bears did with Boggs. If I am not mistaken, didn't Long have to go to the sideline for an ankle during the season, and didn't they play Britton as the guard? That made Boggs as just a backup center, and I am uncertain that they still would not have slid Slauson over instead of throwing him in there sink or swim. Of course, if they did put Boggs in then what I just typed is not true. Just going off memory here. I don't think Brown is over Boggs in any scenario on this team. He is on the way out.
