Who is the Worst NFL Draft Bust Ever?
The worst NFL draft busts of all time are typically considered to be high picks who completely failed to live up to expectations:
Top 5 Biggest Draft Busts
- Ryan Leaf (#2 overall, 1998 Chargers) – Often called the biggest bust ever. Went 4-17 as a starter with more interceptions than touchdowns before flaming out after just 3 seasons.
- JaMarcus Russell (#1 overall, 2007 Raiders) – Massive work ethic and weight issues led to a 7-18 record and 65.2 passer rating. Out of the NFL after 3 seasons.
- Tony Mandarich (#2 overall, 1989 Packers) – Called "the best offensive line prospect ever" but was massively outplayed by the next 4 picks (Barry Sanders, Derrick Thomas, Deion Sanders).
- Akili Smith (#3 overall, 1999 Bengals) – Won just 3 of 17 starts, threw 5 TDs vs 13 INTs.
- Johnny Manziel (#22 overall, 2014 Browns) – Off-field issues derailed his career; he started just 8 games in 2 seasons.
Ryan Leaf is most frequently cited as the #1 bust due to his high draft position (#2 overall), catastrophic on-field performance, and poor attitude.
