I was reading Ron Cook's article in the Post-Gazzete and came across the following passage which has left me stupefied.

Arians admitted the Steelers' pass-run ratio -- 41 pass plays (counting one Roethlisberger scramble) to 17 runs -- wasn't quite what he wanted. He blamed the third-down failures. "We didn't snap it enough. We should have easily been able to convert 50 percent of those third downs. Now, you're talking about maybe another 18 or 20 snaps. Instead of running the ball 18 times for a 4.4 [-yard] average, maybe you run it 28 times for 4.4."

Considering two facts:

1. Steelers ran 58 plays
2. On 3rd Down Steelers ran 13 pass/2 run plays.

Will Someone more adept at navigating the murkiness that is Bruce Arians please explain what the..... was he expecting ?
