It's easy to suggest the "old and slow" Steelers defense was responsible for Terrelle Pryor's 93-yard touchdown run on the first play from scrimmage - the longest run for a quarterback in league history.
It was simply over-aggression and a lack of containment.
Timmons got cut/tripped by Raiders guard Lucas Nix, who blocked linebacker Vince Williams with their pile-up. Wide receiver Rod Streater did a good job sealing off safety Troy Polamalu, who was the only player in a competitive position to stop Pryor.
The hole created on the misdirection was wide enough to drive a semi truck comfortably, but the Raiders had a Ferrari instead. Pryor accelerated and showed his greatest attribute; his speed.
It's tough to find a defender in any era who would have been fast enough to track Pryor down in the open field.
The issue here wasn't the fact the defense simply wasn't going to get Pryor after he moved about four yards past the line of scrimmage. It's the fact the Raiders have run this play multiple times throughout the year, and it should not have taken the defense that much time to recognize it.
Steelers coach Mike Tomlin said after the game, "(Pryor running) has been a component of their offense. I think I led with that on Wednesday."
If nothing else, Tomlin should probably lead Wednesday with something about the propensity of the New England Patriots, Pittsburgh's Week 9 opponents, to throw the football.
And Thursday. And Friday.
