I read this on Steelers.com. I think it's the right move! We need a good draft and with a little depth the Steelers will once again have the best D.

From Steelers.com:

Tomlin spoke to media while at the owners meetings and indicated that the Steelers will stay with the 3-4 defense.

"I know what it does to offenses, I really do," said Tomlin. "It's all about the personnel you have. We have the best 3-4 people in the world, I think. That's what we're going to do."
