The choice belongs to Sidney Crosby and his doctors. No one else can say whether it's wise for the Pittsburgh Penguins superstar center to play again after missing the second half of last season and all but eight games this season because of lingering concussion symptoms. As much as the NHL would benefit from his return, as eager as fans are to enjoy his wizardry and as insistent as observers like Canadian commentator Don Cherry are that he retire, this is Crosby's decision, pure and simple. We can only hope he makes the right choice. And that if he returns, he won't be stuck in another dark tunnel of headaches and confusion six months from now amid questions about living an impaired life beyond the rink.
