First statement false, second statement true.
The run defense is our strength, especially with how we shut down running games in the pre-season. (inb4it'sonlypre-season) However, that was with Gerald McRath, who's suspended for 4 games, so there'll be a weakness there, but I think we'll be fine. The defensive line will be in the backfield quite a bit to stop Bush or whoever runs the ball for you.
The second CB is a toss-up right now. McCourty is a better tackler but got burnt a little bit in pre-season, while rookie Alterraun Verner is a playmaker but is a little overaggressive. Either one is an improvement over last year's starter Nick Harper, and I hope Verner does start.
