It becomes tiresome after a while to keep comparing this season to last season. Mike Holmgren, Gil Haskell and Matt Hasselbeck, among others, were adamant from the start of camp that last season had nothing to do with this season. And yet we keep analyzing this season against what happened last season. It's natural. It's even relevant. It's just a little tiresome after a while.
Now that I've got that out of the way, let me answer an interesting this-season-vs-last-season question raised in a recent reader email.
You can derive the question from the answer: Seattle has averaged 3.63 yards per first-down rush and 6.28 yards per first-down pass this season. Those numbers are down from 4.41 and 8.42 yards, respectively, last season. Those are huge dropoffs.
