Some sites are reporting that he is not flat out retiring and instead are suggesting that he's taking a year off and supposedly will return with another team after 'taking a break'.
This does not seem practical and I'm going to speculate that the insistence that he is announcing retirement is probably what is going to actually happen.
Still, one has to wonder if there is something else behind this and whether we'll ever know the real story. Perhaps it is as genuine as it sounds, he made a decision and sprung it on everyone.
Sure is unconventional.
