I voted yes.
Obviously, a "Notre Dame Man," just taking the phrase at face value, should be anyone who was a part of the ND community, had an impact on other members of the community while he was a part of it, and was shaped by the Notre Dame experience. If people want to change a player's thread title to give him a "Hall of Fame" designation, then "Notre Dame Man" strikes me as the wrong phrase. For instance, was KLM not a "Notre Dame Man"? He was a captain and leader on a team that went to the NCG. Personally, I always thought that "Notre Dame Legend", which I believe was the original suggestion, would be a better phrase. "Notre Dame Man" seems to apply to too many people.
On the other hand, if we want to change a player's thread title when he has 1) been a key contributor, 2) stood out as a leader and/or dynamic personality on the team, and 3) given ND all he has, then "Notre Dame Man" is a pretty good label. If that's what it means, then I am all for Tommy getting the designation.
