College football countdown: No. 20 LSU

Why we might be wrong: This defense is so good, so physical, Jefferson may simply have to not mess up. Patrick Peterson is the best cover cornerback in the nation, and will take away half of the field in pass defense and allow talented FS Jai Eugene to freelance more often. That means various blitz and cover packages — and more turnovers forced. The household names of the past aren’t around on the front four, but it will be as deep and athletic as any under coach Les Miles.
