You guys are watching the Titanic sink and thinking WOW - not realizing the iceberg hit years ago.
2016 World under-20s - 1 bronze medal
2016 Rio Olympics - 2 of 3 relays DQ'ed in the Olympics (including the 4x400), one medal on the last day
2017 World championships - Winning the 4x400 masks what is just an OK worlds for us (Jereem 3rd 200m as well)
2018 World under-20s - No medals, no individual finals
2019 World Championships - No medals
2021 Tokyo Olympics - no medals (first time since 1992)
2021 World under-20s - No medals, no individual finals
This is what happens when you are happy with "just ok" results - it's the sports equivalent to ignoring a slow leak on a car tire.
Flat now.
