Are our thoughts on Steroids?

Arbitrary discussions over lunch with friends, the recent Djokovic Vs Fedex semi final match found its spot amongst the millions of other topics. The match was an amazing 5 setter evoking memories from the Wimbledon Bjorn Borg Vs John McEnroe match, though not as riveting as that one, this was equally interesting and the showman himself saved two match points to take the game away from Federer. The arguments slowly closed in on the style of play as to why 'Serve-Volley' players are now an extinct species and all the top players are now baseline players with more time spent on tweaking the angles on their return. As always, there was a discussion speculating what Sampras or Boris Becker would do when they play against Nadal or Federer or  Djokovic? But after a friendly exchange of fire, what stunned the entire table was a quick, short remark from one of my friends, he nonchalantly said "Every player on the court, be it any sports, are on steroids. What else can explain the power and length of the games today". For a moment I was shocked and I couldn't even contemplate the magnitude of the accusation, this was a very general statement I really felt offended as a sports fan in general. Tennis for instance has evolved over time and current state can be attributed to the light weighted bats, better shoes, power on the racquet, amazing physical training these folks undergo and just dismissing them  in a single statement is ridiculous. I am of the opinion, sports in general may have some blips in the form of steroids and performance enhancing drugs, but to generalize the entire player community for playing better to steroids is not acceptable. It is the adaptability to situation and coming up with innovative measures to counter the other person's strength, which has always been the way to the top and we have seen that happen with Federer and Nadal where they countered serve-volley routine with a strong baseline play with longer rallies. This can also be observed in Murray and Roddick's game (serve-volley again), where they have actually changed their style to increase their probability of winning.

I think this more to do with people's perception after the Armstrong and Agassi episode. I seriously believe it is  pure determination, skill and will power more than anything else that can make a winner out of any form of competition. The recent Nadal Vs Djokovic is a sample to that line of thought.
