10 biggest NFL draft busts in UCLA football history

In his final year at UCLA, McKinley notched double-digit sacks and posted 18.0 tackles for loss, so the Atlanta Falcons, who were coming off a devastating Super Bowl loss, went with McKinley in the back of the first round. Part of the reason that Atlanta blew a 28-3 lead to the Patriots was a lack of pass rush, so McKinley was brought in to be the solution. 

As a rookie, McKinley was a rotational pass rusher, playing all 16 games and finishing with 6.0 sacks. The next year, he posted 7.0 in 15 games and appeared to be on an upward trajectory. However, seven sacks would remain his career-high across his six seasons in the NFL. 

McKinley regressed as he became the starter and drew more attention from opposing offensive lines, then was injured in 2020 and played just four games. His fifth-year rookie option was declined, so he signed with Cleveland where he played 11 games and recorded 2.5 sacks. 

Then, in 2022, one year after winning the Super Bowl, the Rams brought McKinley in for four games, which were the final four of his NFL career. McKinley showed promise as a young player but quickly washed out of the league.
