Syringes and "The Play"

Apparently Roger Clemens' former trainer, Brian McNamee, says he has physical evidence that Clemens used steroids - including syringes with traces of steroids and hGH and Clemens' DNA. I don't really understand a few things about this. First, who keeps syringes after using them? Second and more importantly, how can they tell how old the syringes are, and whether or not the blood and steroids were somehow associated with them at the same time? For example, what is the difference between a needle / syringe that was used to inject steroids that has some blood on it, and a needle / syringe that was used to inject someone with something else, and then had steroids put into it? For that matter, since blood should only go into the needle, why not mix and match needles and syringes? It still sounds like a lot of "He Said / He Said."

The Eli Manning to David Tyree play that seemed almost miraculous during the Super Bowl should just be nicknamed "The Play." Right now, everyone knows what that refers to, so why not just dub it so? We already have "the catch" and "the escape followed by helmet catch" is too long a name. The local papers all have contests to "name the play."
