curious? which part do you not understand?
My "curious" comment was due to the question of whether this might be the result of a career's worth of steroid use. Also, this is the second Steeler lineman to die young. A third (Terry Long) unsuccessfully attempted suicide a few years back. Not to point this all at the Steelers, add also, the story of the Oakland Raiders center who skipped out on the team at the Super Bowl a couple of years ago only to be found wandering in a stupor early Super Bowl Sunday morning.
While the number of NFL Lineman who have had problems is relatively low in comparison with the rest of their teammates and shouldn't be considered "alarming", I do find it curious.
