The last time an Olympic 100 looked this good was nearly a quarter-century ago, when Johnson rumbled down the track to blow out Lewis with a 9.79 that astonished everyone in Seoul. It wasn't long before Johnson was running for a plane at the airport, chased out of the country after testing positive to the steroid stanozolol.
You want to believe today's sprinters are clean, though Gatlin's positive test in 2006 makes it difficult to totally believe anything. Track is a sport long dogged by doping problems, and as long as times keep dropping, there's always going to be suspicion surrounding the top runners in the world.
Hopefully, the drug testers have done their job. Hopefully, the runners have resisted the temptation to cheat.
The race that could define these Olympics is Sunday night. And it's way too good to spoil.
