As the preseason begins, here's hoping for bigger and better things (although, honestly, I'd settle for the status quo). It's strange to think that my team has only had two coaches in my lifetime--helps explain why I was so sad to see Cowher go. Now that 'Cowher Power' is gone...what's next? I'm hoping it's not 'Bottom with Tomlin,' but then again, I've always been a pessimist. Perhaps Steeler Nation will be pleasantly surprised.
