You can't be happy about doping at all, it's not good for the sport. But over the years we're doing a better job, it's getting clean and we're catching up to a lot of athletes. There's an understanding that, listen, if you cheat you will get caught. Over time the sport will get better. I said a couple of years ago it had to get really bad, when there's nowhere else to go but up. The only way track and field has left to go is up.
