Mike Tanier:
I sincerely believe that in 20 years, we will be watching and enjoying football, and that concussions and post-concussion symptoms will be manageable medical problems that we have learned to avoid in many cases and treat responsibly in the others. American football used to have problems with severe spinal injuries and on-field deaths, first at the turn of the 20th century and later before World War II. Rule, equipment, and attitude changes have made these tragic events rare. Concussions will never be quite as rare, but I believe long-term concussion symptoms will come to be contained as medical knowledge grows and football practices evolve.
