Browning, howbeit imperfect, should obviously start over Borland. The latter hasn't improved in two seasons and is slower than offensive (Cincy game) and defensive (Haskell Garrett last year) lineman.
I'm also beginning to think that Gant would be a better option at SAM. He's showing up more early in his career than Werner has in 1.5 seasons. I'm calling complete and total bulls*%t that Werner is "one of the top guys at his position."
EDIT: Borland and Werner are albatross that are preventing this defense from taking off and being one of the best defenses in the nation.
