I'm of that general mind set as well; however, medical staffs can make mistakes, too, or get pressured into clearing someone when not ready. I think the Dallas medical staff did Roy Williams dirty when they cleared him to play again when he broke his forearm in 2008. They cleared him and he immediately injured his forearm again.
It is fascinating that this is happening. The evolution of medical procedures is great. I hope we get quicker returns for many of the common major injuries in both sports and in general life. There will be a point when a player comes back within a few months or even weeks to injuries in the past ended careers.
