The Hawks typically do not deviate much from their base scheme during the regular season, but it seems like they do introduce more wrinkles during bowl prep (I actually thought they did some pretty cool things in their B1G Championship game defensive game plan). I wonder if they will consider taking a page out of the 2002 Patriot's Super Bowl game plan. No matter where Marshal Faulk went on the field, they had someone assigned to hit him before he could get out of the backfield or off the line, and then they had a DB in position to cover him after the initial beating was dealt. The Rams put up some yards, but Faulk was relatively contained (130 total yards, no TDs), and their scoring output was far below their average.
Both the front and the back of the defense would really need to be on point to cover for the gaps left by devoting so much attention to one player. I think I would prefer the Hawks take this approach over letting the guy who is clearly Stanford's best offensive player beat them.
