Every year the US leaves some of its best people off the roster. People like Hoey, Cunningham, Kovacs, Kelati, Wiley, Kessler, Weyment, etc. this year. The most glaring example of the past was defending world champion Dan O'Brien in the decathlon; he went on to set the world record shortly after failing to make the Olympic team.
It's time to adjust the way we choose our teams. While the "top-3 go and the rest go home" format is exciting, it always means the US sends less than its best team.
It is time for a hybrid format similar to the Q and q system we have for advancement to finals.
A lot of people love the excitement of the current system. Let's keep it but reduce it: top-2 are automatic qualifiers "Qs".
The third spot should go to the person judged to be the best non-qualifier "q". In order to keep it objective rather than subjective, a system can be devised that creates a score for each athlete, similar to the system once used by the Bowl Championship Series to rank teams in college football. Things like World Rank, Season Best, Head-to-Head Record, etc., can be converted to points and the athlete with the highest point total gets the third spot.
Someone like Dan O'Brien would certainly have been the "at-large" bid for Team USA and probably would have won gold for us.
