How will the Jacksonvile offensive be affected by the loss of both starting offensive guards? Is the running force with Freddie and MJD gonna be slowed down?
- Michael Gus, Kissimmee, FL

It, um, doesn't really look good now that Vince Manuwai and Maurice Williams have both been placed on the IR. I really like Fred Taylor, and was glad to see him get the recognition he's deserved last year, but he is 32, and he and Maurice Jones-Drew really struggled against a physical Titans team. Which is a troublesome sign, as the Jaguars have built an identity on being a physical team on both sides of the ball. But if you take away that dimension to their offense, things don't look very good, especially if Jerry Porter's bum hammy keeps rearing its ugly head. Do you really trust David Garrard to carry a team for an entire season if the Jaguars can't get their run game figured out? I certainly don't. And the Jags face some physical defenses this year in Buffalo, Tennessee again, Pittsburgh, Minnesota, Chicago, Green Bay, and Baltimore.

But there are other players whose value just changed with these injuries as well. They're not replacing the player in question, but the loss of that guy changes their own value – some in good ways, others in bad. Let's take a look.

Tom Brady's knee: And sure, Cassel gets himself a gig. But another first round fantasy pick also loses a decent amount of value in Randy Moss, who will now be trying to catch passes from a guy who has never had a starting job since high school. Wes Welker, ranked at or near the top-10 in WR himself, also loses value – though presumably less because he tends to run shorter routes that should be easier on what amounts to a rookie QB.

Vince Young's knee: Unless you play in the deepest of leagues, you don't own, nor did you really even consider, starting WRs Justin Gage and Justin McCareins. In fact, you may have been unaware that starters share the same first name. In truth, Collins is a better quarterback than the injured Young, so the two Justins both get a bump, albeit a small one in value. At RB, Chris Johnson's value spiked up with his performance in Week One, and there's no reason for that to come down without Young behind center. LenDale White also probably deserves to get a bit more love, since there should continue to be plenty of carries to go around.
