Although I don't know much about the details, I've heard the NFL's collective bargaining will include possibly adding HGH to the drug testing program. Many feel that it could help reduce serious injuries and concussions. Some fans think HGH (and other) use is rampant in the NFL and the quality of the game may suffer if they test for it. While most MLB fans wanted all PEDs to be eliminated from the sport, many NFL fans don't have the same attitude. What is the rough estimate of NFL players that use HGH or other PEDs that are not currently tested? Do these players begin using in college or when they enter the league? I've heard HGH can be really expensive and hard to find (compared to steroids). One radio host that I really respect had a difficult time putting a percentage on the NFL players that may currently use PEDs not currently tested.
