First and foremost: I'm not a doctor. Far from it. That being said, I've done a little research into the condition that Stephen Weiss described during the media conference call today.
Assuming total honesty on Weiss's part I've come to believe that he is most likely suffering from a condition known as Positive Ulnar Variation. If one were to hold their hand out, palm facing inward, the thumbs up bone is the Radius and the pinky down side is the Ulna. From that position, rotate your thumb outward (if you have your right hand outstretched turn your thumb to the right) 90 degrees to end up with your palm facing up. The condition that Weiss is probably suffering from causes one's hand to angle outward (again, if you're presenting your right hand, point your middle finger further to the right, a little at first then as far as you can) more than is natural. Try holding your hand in that palm up and outward point position for a few seconds. Maybe 10 or 15 seconds. It gets kind of uncomfortable quickly. Now imagine you're physically unable to return your hand - and the muscles and tendons that move it - back to their natural, relaxed, position. Could you hold that pose for a over a year? I'm pretty sure I couldn't.
I've been quite vocal with my criticism of Stephen "The Guy We All Wanted To Be Captain Eight Weeks Ago" Weiss's play this season but give this new information I kinda feel like a jerk.
