As was said, when 65% of your play calls are runs, you've got to look at yards per attempt and not total yards as an accurate measure of passing success. Against Miami Klein had his best day at 7.4 YPA, but I agree that's not enough. IMO we need to get that over 8 and hopefully closer to 9. Again, this assumes we stay at around 5 YPC in the running game. What won the game in Miami was an excellent 6 YPC on the ground that improves to an even more impressive 7.3 YPC when you take out 27 yards lost on 4 sacks.
If Klein has a 300 yard passing game, it likely means very bad things for K-State's offense. I could see a 200+ yard game coming though, likely this weekend.
