Is it true that the Bears have a team doctor prescribing steroids for immune system regulation?

Could be. I would say though that most of the players in the NFL have or are still taking some kind of performance-enhancing drugs. The league believes the same, but are afraid to admit it because they do not want the backlash like baseball got. Besides they are still trying to live down the 80's rampant steroids use.

If I had to put a number of the amount of players using steroids in the NFL, it would probably about 60%. If a punter (Todd Sauerbraun) uses steroids, then you can believe that a lot of players are using also.

More than likely, not. Do you think the NFL would say, "It sounded fishy to us, but since the team doctor is prescribing, it MUST be legit!" You rarely get guys that rich to be that stupid.
