That slide should be the last play he executes in the NFL. That's just absolutely inexcusable. The whole "going to war" and "warrior" euphemism is over-used in sports, but you want a guy who you know is going to leave it on the field for the win. That was all about self-preservation when there was still a shot to get that game (albeit a long shot). If I am on that offense, or the team as a whole, I absolutely do not trust Weeden.
Church is out there without half his lip. Lee is out there looking like he took an uppercut from Tyson. Witten might as well have no ankles. They're all out there battling and this tool slides in the open field with a 1st down there for the taking. Seriously, his performance is one thing, that play though... Get him out of here.
