The NFL announced last month that players were diagnosed with 281 concussions in 2017, which represented a new high since the league started tracking total concussions six years ago and was a number that NFL Chief Medical Officer Allen Sills called a “disappointment.”

During a press conference in Minneapolis on Thursday, NFLPA executive director DeMaurice Smith said that there were also more than 400 concussion evaluations during the season. Smith had a different reaction to the rise of those numbers.

Smith said it was “a positive” that more players are being evaluated for concussions because it is a sign that the NFL and NFLPA are “smarter and better about delivering” the kind of medical care that led to the establishment of the concussion protocol in the first place.
