ACL Tears & Hit Rates: A Story of Statistics
Twitter: @DoctorChapFF
The dreaded ACL tears. This debate has been going around Twitter on who will bounce back and who won’t - thousands of back-and-forth arguments over Sutton, Saquon, Kelvin Harmon, Albert O, etc. For this reason, I decided to compile ALL of the ACL tears from 2012-2019 (8 years worth) and find the statistical analysis of “hit rates” and seasonal improvements in play. This is what I’ve found:
77 Total ACL Tears Since 2013 (Excluding 2020)
11 Rookies (Excluded from Pre/Post ACL comparison only)
Only 1 Rookie ACL tear has come out to produce a WR2/RB2 season or greater – Dalvin Cook 1/11 (9%)
33 Players never played another snap again: 33/77 (43%)
7 of these players “hit” (WR2/RB2 or >) in a season post ACL injury 7/77 (9%)
8 total players showed improvement from pre-ACL season to post-ACL season: 8/66 (12%)
On the surface, this already doesn’t look fantastic for these players, but it’s better to break it down a few ways to get the best idea of who has the best chances to bounce back. Below I break it down Round by Round, Player Age, and then WR vs RB.

This data here can be used as a reference and gives you a few different ways to get a probability of your favorite bounce-back candidate actually bouncing back.
What I’m seeing here is this...
Round by Round
At least a 50% chance of not playing again if UDFA-5th round
Results slowly improve from 4th round and up
Hit rates are very low unless drafted in the 3rd round or higher
Age
Hit rate varies here
0 WR’s Hit when they tore their ACL before age 24 (0/10)
0 RB’s Hit when they tore their ACL after age 23 (0/20)
WR vs RB
There seems to be a much higher “hit rate” probably of a WR compared to an RB following an ACL injury.
When you look at standard “hit rate” vs. post ACL injury “hit rate” there is clearly a decrease from one to the other.
Final Analysis
As @FBInjuryDoc always says, no injury is created equally. There are so many factors that go into each player’s specific injury and history (i.e Age, Round drafted, previous history, etc). What I’m looking for is a pattern when I am bringing this over to fantasy and dynasty football. The verdict is still out on a few of these players if they will eventually hit. This is why I wanted to start this database and will continue to update it, year to year as we get more cases and results.
Oh, and do I think Saquon will Hit again? Absolutely!
