If it looks like Notre Dame’s defense is bigger than seasons past, it’s because it is. Consider that the projected starting 2011 defense, even with one less defensive lineman, is 205 pounds heavier than the 2006 defense. (Numbers courtesy of JRT)

If you’re looking for a reason to believe that the Irish can play dominant defense, here it is. Three NFL sized defensive linemen? Check. Big, strong, physical linebackers? Yep. In the past, it was the front-seven of the Irish defense that didn’t physically stack up. Not anymore.

This was always a thing when it came to Weis. The players graduating, going into the draft ALWAYS were too light or not strong enough. It's nice to see this. I was skeptical going into last season but now I'm excited.
