After what Detroit Lions QB Stafford and his family had to go through with that false positive, the NFL really needs to step this up! For all the excess monies the NFL has generated and will generate, the recent rash of false positives is mediocre effort on the NFL organization.
Being accurate helps to see an NFL season!
I guess false positives are like INTs such that enough INTs can delay a post season. Why continue on this path? C’mon, NFL, dump in more resources or find a better lab, which might cost more, but accuracy is ideal!
