2012 NFL Concussion Report Post Week 13 – LATE

11 Dec

Guess the holiday season has many people behind on tasks, including yours truly.  Anyhow, here is the report from after 13 weeks in the NFL.  The report for week 14 should make it to this space by the end of the week (cross your fingers, ha).

During Week 13 we found 15 concussions, seems the weekly average is going up.  We now have 142 regular season concussions – 190 since camp opened.  NOTES: The offense continues to hold roughly a 10% advantage in concussions, which is weird it should be a 50/50 split…  Including preseason DB’s have more concussions (48) then the rest of the defense (38) – 36/28 split in regular season…  Interestingly RB, TE, OL, DL and LB all have similar occurrence; WR and DB’s are higher and QB’s way low…  I think we are going to see a new season “high water” mark, credit to Will Carroll for calling this before the season…  ()’s represent last week’s numbers…;

  • 142 Concussions/head injuries (127)
  • 10.92 Concussions/week (10.60)
  • 185 Projected Concussions (180)
  • 0.73 Concussions/game (0.70)
  • 12.90% InR (12.49)
  • 10.95% EInR (10.61)
  • 70 Offensive (78) – 57 Defense (64)
  • Positionally Speaking
    • QB – 7 (7), RB – 14 (16), TE – 13 (14), WR – 24 (27), OL – 12 (14), DL – 10 (13), LB – 15 (15), DB – 32 (36)
  • Team Breakdown
    • OAK – 12
    • DET, JAX – 8
    • CLE, IND, KC, WAS – 7
    • NE, NYJ, PIT – 5
    • CAR, CHI, DAL, MIN, NYG, SEA, SF STL, TB, TEN – 4
    • ARI, BUF, CIN, DEN, GB, MIA, NO, PHI – 3
    • BAL, HOU, SD – 2
    • ATL – 1
    • NONE – 0

Our definition of Incidence Rate (InR) is projected concussions/45 players taking the field per team per game, our definition of Epidemiological Incidence Rate (EInR) is projected concussions/53 man roster per team.

Comparing to past seasons the following has been found after Week 13: # (2011, 2010):

  • Regular Season Concussions – 127 (122, 119)

    As a coach, I’d like to offer my interpretation of this stats (and thank you very much for your work in compiling them). First of all, you need to consider how many players at each position are on the field in each game. There are always going to be five offensive linemen and one quarterback. An NFL offense will also typically play one RB, one TE, two WRs, and the eleventh player will be an extra WR, TE or occasionally a 2nd RB. On defense most teams use 4 DL and 3 LB, a few reverse that, and all of them regularly use 4 DBs and often bring in a 5th by pulling a LB or perhaps a DL. So I’m guessing the average play has about 3.7 DL, 3 LBs, and 4.3 DBs.

    So adjusting for the number of players at each position, RBs have by far the most concussions with about 14 for each typically on the field, followed by WRs and TEs with around 10. There’s a substantial drop-off to DB and QB, another to LBs and DLs, and OL has the lowest with less than three per player typically on the field.

    This suggests that the biggest threat is from the high speed collision rather than more routine contact. It would be interesting to see a breakdown of how many concussions are sustained by a player who is carrying the football. I suspect it is at least a third of the total. On defense, it makes sense for DBs to get more concussions because both they and the ball carriers are far more likely to be running at full speed when they make contact.

    I suspect that it also means that the recent focus on avoiding helmet to helmet contact is having an impact. It is easier for a defensive player or a blocker to keep his head out of a collision than it is for a ball carrier who is trying to avoid multiple defenders at once. It is also easier to avoid hitting the head of a QB who is trying to throw a pass than that of a RB or receiver who is trying to run you over or make a cut out of your way.
