His fears aren't totally unfounded, we're 22nd in the league in yards per carry, at 4.3...
Our total rush defense standings are skewed by the fact opponents haven't really run the ball all that much against us-- 22.3 times, next to last in the NFL...
So it is perfectly legitimate to worry about what happens when we face a team determined to run the ball against us... and Seattle is second in the league in rushes per game, at 30.8... they also average 5.4 yards per carry, 2nd in the NFL... if they run the ball on us 31 times, and average between 4.3 and 5.4 yards per carry (split the difference, call it 4.8 yards per carry), that would be right at 150 yards rushing for the game...
Our run defense is gonna have to step up big time in this next game... I'll be interested to see if they can do it...
