They also have a pretty ridic running game.
It also affects us less because of our pass catchers at TE. We have tons of options that most other teams don't have. I mean look at Houston, they have a strong running game, a number 1, and had Owen Daniels but last year he didn't even play most of the season. After that it's freaking Kevin Walters? Having depth at the WR position is a luxury, and it's one that you don't really need if you have a good QB and a strong running game. We obviously only have half of that, but we have more talent at pass-catcher than most teams in the NFL, too. Most teams are lucky to have a #1 and a decent TE. We have possibly two #1s, the best TE in the league, two decent backups to that TE, and one of the most effective backs in the league catching passes.
tl;dr there's no reason for us to be overly worried about who our 3rd Wr is or fretting on what we'll do IF someone gets injured.
