Now that Jim Zorn has shown he’s not the worst coach in America, Redskins fans can focus on the final challenge this season: beating San Francisco (6-9).

We’re Toasting the Defense: It’s no small feat to enter Week 17 in the NFL ranked fourth overall on defense — ahead of both the Giants and the Titans — but the 8-7 ‘Skins have done it this year.

This should make Sunday’s matchup more intriguing, since Mike Martz, architect of The Greatest Show on Turf, is now the 49ers’ offensive coordinator. But the ‘Skins actually have a decent history facing Martz-coached teams. In fact, they’ve never lost to Martz either as an offensive coordinator or head coach. Martz, of course, spent a brief stint in Washington as quarterbacks coach under Joe Gibbs.

Both the Skins and 49ers are coming off dramatic Week 16 victories — while the Redskins were making a goal line stand to beat the Eagles, Maryland product Shaun Hill churned out 14 points in the fourth quarter to help San Francisco beat St. Louis 17-16. This was right after he was almost benched for poor play in the previous three quarters, so expect him to have a little more confidence Sunday after the San Francisco surge. Or at least don’t count him out before the clock runs out.
