In my opinion Boyd Cordner needs to seriously think about his future. He is someone who has made it to the highest levels of the game and has nothing left to prove or accomplish. He has captained his club, his state and his country.
Boyd has suffered many head knocks and concussions and seeing him staggering from the field after a somewhat minor bump would have to be concerning for him personally, and then seeing him return to the field , in my opinion, is an extremely ugly look for the game.
Some serious questions need to be asked when a such a minor bump can leave him suffering clear symptoms of concussion. We are only scratching the surface as to the effects of CTE (Chronic Traumatic Encephalopathy) on the brain and Boyd is a young man with a a long life ahead of him.
That life needs to be protected by the league, and players need to consider their future, because we are learning more and more that repeated head trauma can have devastating long term effects on the brain and the future quality of life for the people involved.
