Ewan McGrady, won Rothman's medal. Not really underachieving.
Julian O'Neill played Origin and played at the best of his ability, he wasn't that talented really. I'd say John Sutton has shitloads more ability than Julian O'Neill but has underachieved more than any player I've ever seen.
Alan Cann represented state and country. Wasn't the most gifted of ball playing forwards either but played to his ability and even well above it for a few years.
Mark Geyer played in a time when there were a shitload of great forwards around and still managed to play for state and country.
Olsen Filipaina represented New Zealand in Tests for 10 years!
I'll give you the rest, but f**k you got some of them completely wrong.
You desperately need to read the thread if you think for one second that you are contributing anything new about Mcrgady, Geyer, or Fillipaina.
But a short synopsis: Geyer and McGrady both ended up in bush footy after their 1991 heroics. How many 27yo Rothman's medalists have totally disappeared from the game less than 3 years after winning the medal, playing 5 games combined in two of those years, never to play origin or tests? A rothman's medallist who had a career of only 64 games is not underachieving? Really? Olsen Filipaina was man of the 1985 series while playing reserve grade for Easts. He completely underachieved in NSWRL whereas compared to his international achievements.
I totally disgaree with you on O'Neil's talent, and Cann would not have been cut by the Super League Broncos after his first and only origin performance for achieving. He certainly should have played Origin well before when you look at his grand final heroics had he not underacheived. And he never played for Australia? Deleted from the game at what, 27? So unless he got a career ending injury, underachiever for a guy who played at the Broncs in the 90's, could rip a grand final apart, and former Aus Schoolboy.
