At least it's possible on this list anyway:
I knew KC was an old fart for an NFL QB, but I didn't realize how far up this list he was. 14th in passing yards all time. A couple of good seasons, heck one outstanding season, and he'll pass up Joe. Argh! Look who's at number 1!! Make him go away! 'course that guy is probably #1 on the all time interceptions list.
I'm surprised that Testaverde is shown as inactive on this list. I figured he was still playing for somebody ;-).
