If those are the honest reasons for retiring, all power to him. If he stuck around, he'd be distracted or unhappy and not play to the top of his game. However, Thomas being a goalie for the Olympics is a stretch. I mean here's probably the team USA roster:
1) Quick
2/3) Miller (appreciation nod, rises to the occasion as in 2010)
3) ???
Probably Corey Schneider based on talent or Howard due to pulling IIHF duty this year and being solid. Any other USA goalies worth mentioning that I can't think of?
Is Tim Thomas on his absolute best better than either? Yes to Howard, big maybe at best compared to Schneider. Except Schneider is significantly younger. Miller is the "aging" pick nod, don't need two of those. If it's Schneider, I'd slot him as the #2, but if Howard then Miller at 2. Also kind of "If picking right now" scenario.
