AFC West mailbag

Posted by ESPN.com’s Bill Williamson

Mid-week mail call:

Doug from Ohio wants to know if Elvis Dumervil can have a James Harrison-like impact for Denver.

Bill Williamson: That would be asking a lot. Harrison, a star for Pittsburgh, is one of the best defensive players in the NFL. The Broncos will be happy if Dumervil can become a 12-15 sack man. Dumervil, though, looks like he will flourish in Mike Nolan’s 3-4 defense. Switched from end to linebacker, Dumervil was dominant against Cleveland on Sunday as he had four tackles. Dumervil is a type of player who has produced in pass-rush situations since high school. I think he can have a major impact in this defense. But thinking he can be as good as Harrison, may be asking a lot.

Daniel Nichols from San Diego wants to know if I like the Chargers could switch to a 4-3 defense with Jamal Williams out for the year with a triceps injury

BW: I think you will see looks in which San Diego plays the 4-3. Defensive coordinator Ron Rivera likes to do that, anyway, now and again. With Williams, a great fit for the 3-4, out, you’ll probably see Rivera take advantage of the 4-3 front more often. But this defense is designed to be a 3-4 look, so it’s highly unlikely it will be completely altered as a result of Williams’ injury.

Randy Reber wants to know what I think of the Denver Broncos after their 2-0 since I was a harsh critic of the team in the offseason.

BW: Fair question, Randy. I think the Broncos have a ways to go before showing they can stay in the race. But they have looked good so far, especially on defense. The fact that this team is 2-0 is impressive. I was, at times, a harsh critic. I wouldn’t have been surprised if Denver went 4-12. Well, they are halfway there. The key for Denver is to survive a tough 10-game stretch that begins in Week 4 at against Dallas. If Denver’s defense can hold up and the offense can continue to make timely plays, Denver could have a chance to be competitive and that is more than lot of people expected.
