For what it's worth, my brother-in-law is a Bears fan and season ticket holder, and I used to live in Chicago, so I've kept an eye on them over the years. Not that it means anything, but I remember watching Orton his first couple of years in the league, and I have to say, I remember thinking he was the worst QB I have ever seen play this game. Dude was just unwatchable.
I have no idea how he managed to survive and make a long career of it, but man, he was just God-awful those first few years. EJ is light years ahead of where he was back then.
