As for Akers' long-term potential … this definitely complicates it. Ruptured Achilles are some of the toughest injuries for professional athletes to come back from, and the history for running backs is very, very tough.
It's hard to find a comprehensive list of running backs who have suffered an Achilles rupture, but I think I have a pretty definitive list and it is … ugly. So, so ugly:
- LenDale White, 2010 (age 26) -- Never played in the NFL again
- Andre Brown, 2010 (24) -- Out of the league by 2013
- Mikel Leshoure, 2011 (21) -- Out of the league by 2013
- Earnest Graham, 2011 (31) -- Never played again
- Kendall Hunter, 2012 (24) -- Played 16 games, had 80 touches in 2013, never played again
- Beanie Wells, 2013 (26) -- Never played again
- Vick Ballard, 2014 (24) -- Had torn ACL in 2013, Achilles in 2014, never played again
- Arian Foster, 2015 (29) -- Cut midseason following year, never played again
- Branden Oliver, 2016 (25) -- Eight games the following season, never played again
- D'Onta Foreman, 2017 (21) -- Played one game in 2018, out of league in 2019, returned as reserve in 2020
- Isaiah Crowell, 2019 (26) -- Out of league
- Marlon Mack, 2020 (24) -- We're still waiting to see, but …
It's about as bad as you could possibly imagine, but it's also not quite as bad as all that makes it seem. The truth is, the sample size of running backs who suffered a ruptured Achilles is very small, and you can at least make the case that Akers' combination of age, talent, and draft capital make him stand alone from this group. He'll get more opportunities than a guy like Ballard did coming back from his injury, due to his place on the depth chart and how much the Rams invested in him in the draft.
Of course, it's also easier to say that the likes of Foreman or Leshoure just weren't that good, or that Wells and Foster were already on their way out by the time of their injuries after we know how they fared.
And you can point to the likes of Demaryius Thomas and Terrell Suggs or go cross-sport to Kevin Durant and find examples of players who came back from this injury and continued to thrive. This isn't a zero-percent chance kind of injury, after all.
But, look for whatever evidence you can find -- this piece I wrote back in 2015 about Achilles tears in the NBA, say, or actual research from medical/scientific journals written by people who are actually smart -- and it mostly points to the same, troubling, but inescapable conclusion: A ruptured Achilles is one of the worst injuries a high-level athlete can come back from. There have been medical advances that make it more likely, but all things considered, this is just a really tough situation.
