Using Lance Armstrong as a template, here are some attributes of Bolt's career that should have served as warning signs:
- Huge early promise as an athlete (a precursor rather than an indicator)
- Huge leap in ability over a short period of time
- Astonishing athletic achievements (untouchable)
- Dirty Sport (that suits doping — huge infrequent events, large off season, one primary physical attribute)
- Dirty Team
- Questionable coaching/medical staff
And here are some that may indicate why he wasn’t exposed earlier:
- Huge sponsorship deals
- Big personality
- An inspiration to millions, raising awareness of a sport
- Never tested positive in a test
