Fortunately, there are lots of great Zips players from whom to choose in those years. Unfortunately, there are lots of great players who can't all be selected. No right or wrong to this; no way to prove which of these players would play better together than others.
Soccer America may have chosen Kofi Sarkodie as a better player than Darlington Nagbe in 2010, but the 2010 MAC Hermann Trophy (best player in D1 college soccer) went to Darlington Nagbe. Kofi was a phenomenal RB for the Zips... no question. DeAndre Yedlin may not be perfect; no one is. However, DeAndre Yedlin has gone on to be the most successful professional to have ever come out of the Akron ZIps Men's Soccer program. Started his first year with the Sounders; playing in the EPL; 2014 USMNT World Cup team, etc. So, if someone votes for DeA over Kofi, they have reason to do so. There are also reasons others may vote otherwise.
Choosing between 3 great goal keepers was equally difficult. There were reasons to vote for any of them.
Voting for all of the other positions is going to be just as tough. In the end, to me, this all decade team is just something that gives us reason to think back on these great players and how lucky we've been that they chose to come to Akron, be a fellow student and alumnus, and to play for themselves and us.
EDIT 2/25/20: convinced now that there is a right and wrong approach to this voting.
