I have a feeling if he is close to capable to playing, he would. With expansion, he may find his way back for atleast one or 2 seasons. Thus it will be interesting if he decides to push his way off Robidas Island to coin a phrase and work something out with the Leafs so he can.
Players decline physically way earlier than most assume. Folks seem to think everybody plays until their late 30s, when in fact that's a rare occurrence.
I wouldn't say its that rare of an occurrence just that those who do play late into their 30s can sometimes be completely random. Shawn Thornton for example is pushing 40 and is still playing where as Heatley who was a 50 goal scorer was out of the league by 33.
