Interesting, that when the predictions for the NCAA basketball tourney are looked back on, the talking heads that told us what would happen, don't fare well. I agree that the science is not to be denied. If Greene can do what he does now without his legs "strong enough", just imagine what can be with legs becoming strong enough, and used more! I will take 4 great Lincecum years, more than a 4 ish ERA inning eater (Brake Radke?) that last a longer time. All pitchers are going to break down. Their time, like running backs, is limited, and they know that going in, or should. Even with the science, we are guessing, just convincing ourselves it is a better guess with better probabilities. Until they go down anyway. Which they do with ever increasing frequency, regardless of the better knowledge and science. It's fun to talk about, though. And then there are unexplainable occurances, like Sandy Koufax (bright and quick and violent delivery) and ageless Nolan Ryan, and Randy Johnson...... and Clayton Kershaw.
