Defense wins championships; the adage is proven true every year.
This year, the top two defenses in the country will square off in the National Championship. Two more great units will face each other in the Fiesta Bowl.
And arguably, the Florida Gators are where they are because of the letdown on defense in the SEC Championship Game. Getting stops consistently is the most crucial part of the game.
Who will field the top defenses next year? I've weighed returning starters, recruiting classes, and strengths or weaknesses in the coaching game to project who the top 25 will be in 2010.
There were some surprises, but I'm confident that if all the right guys return, this list won't be too far off 365 days from now.
