Reading this piece by Husain Abdullah on why he retired at the age of 30 confirmed a couple of things for me. First, Abdullah is a special person. He explains the rationale behind his decision to retire and I can't help but respect how much thought went into after reading that.
Second, the Chiefs really do seem to take concussions seriously. I noticed in the past couple of years that it seems like players on the Chiefs who suffer concussions seem to be out longer and longer. I think back to the Jeremy Maclin concussion when everyone thought he would play and the Chiefs seemed to be very cautious. And I look to this passage in Abdullah's piece when he compares getting a concussion in 2011 vs. 2015.
When I was with the Chiefs and I suffered my fifth concussion, it was completely different. They went above and beyond to try to diagnose the concussion, and to try and rehabilitate me. There was a protocol — different steps you had to complete and benchmarks you had to reach before you could step back on the field. It wasn’t just, When you’re good, you’re good.
You really do have to go read Abdullah's piece. He makes a great point in explaining the difference in how he approached his concussions last season and 2011 in that it's only four years difference. Imagine how much we will know about concussions in 2018 and 2022.
