But Williams has looked slow and confused, and he's been beaten a lot. I'm not sure Reid can look any worse. And at 6-feet-7 and 340 pounds, he's the size of a small building. At least it'll take pass rushers longer to run around him on their way to Joe Flacco.
The Ravens could rotate some young guys in the defensive line, too. I think it's safe to say that Pernell McPhee, Terrence Cody, Ma'ake Kemoeatu and Arthur Jones haven't exactly set the world on fire with their play.
I give McPhee credit: the big defensive end came out this week and basically said he stunk, that he doesn't have the explosiveness he needs after two knee surgeries.
Who knows, that might even motivate a guy like Cody, the big nose tackle the Ravens took in the second round of the 2010 draft who's been more or less a bust so far.
As Harbaugh pointed out a few days ago, there's no need to make wholesale changes with this team. Again, the Ravens are 5-2, not 2-5.
But getting a look at some young guys and seeing if they can contribute and spell some veterans makes sense in the long run.
And the long run — deep into the playoffs — is what the Ravens say they're all about.
