Bill Simmons' NFL Playoffs Outlook

"And since I have nothing else to add before we get to the favorites, here are some of my favorite football e-mails from the past two weeks:

From Jason M. in Miami: Concussions have cut short the careers of many professional athletes in recent years: Troy Aikman. Eric Lindros. And likely now Wayne Chrebet. So, here's my question: Do you think that's what cut short the career of B.A. Baracus and essentially brought down the entire "A-Team?" Think about it. Every time they flew somewhere, they had to knock him out to get him on the plane/helicopter. Well, after a while, you know B.A. must have been suffering some sort of postconcussion stress syndrome. I bet all those blows to his mohawked coconut pushed him and The A-Team into early retirement. Your thoughts?"
