The "REAL" Underdog was an older man and he passed away years ago...only person I EVER KNEW that got his actual plays was Brian Mac?? Be careful with the Green Bay play as also anyone that knows Underdog knows he only has 1 play (Max) per day??
Honestly, it is very difficult to confirm a BW play. And, more importantly, it is virtually impossible to get all of his plays, including buy backs on games.
