The doping ban is still fresh on Sinner. He'll be on the radar from now on. The usual iceberg of doping excuses:
1) The doping entered the system after a massage/my doctor gave it to me/staff negligence
2) WADA agents couldn't find him anywhere for a test (hiding nearby)
3) It's a federation's conspiracy on the athlete, for speaking out... about something malicious in the organization.
He got away with the lightest ban, should be very careful now. I view Sinner as one of the frontrunners to form new generation's big rivalries.
On the other hand Italian sports are leading, way ahead, the charts in anti-doping violations. Cycling, long-distance running. Might add Juventus of the 90s.
