Evans, UCI's career leader with 31 goals, was the Big West Conference Offensive Player of the Year each of the last two seasons and garnered third-team All-American honors in 2006. He was the Big West Midfielder of the Year in 2004 and a member of the under-20 men's national team.
Having participated in the MLS player combine completed Monday in Fort Lauderdale, Fla., Evans was expected to be picked in the first four rounds.
Dunn, a dynamic defender who earned first-team all-conference laurels as a junior and second-team honors this season, said he learned only Thursday night that he was on the list of players expected to be drafted.
Both he and UCI senior Anthony Hamilton were projected to be picked in next week's MLS supplemental draft.
Evans, reached by phone Friday, was still energized after being serenaded with chants of "Br-ad Ev-ans" by Crew rooters, many of whom he signed autographs for and posed with for pictures.
"It's surreal," Evans said after being the second pick of the second round, the first selection by Columbus, which had traded its first-round pick. "When I was 14 or 15, I never in a million years would have thought I'd be here. It's always been a dream, but who would have thought?"
Columbus Coach Sigi Schmid, a former UCLA coach for whom Evans played on the under-20 national team, was well aware of Evans' ability, Evans said.
"I talked to Sigi [Friday] and he said he has nothing but confidence in me," Evans said.
Evans was a defender on the under-20 squad and UCI Coach George Kuntz said Schmid may utilize Evans as a defender who can score.
Dunn, who stopped watching the draft on television in order to prepare for an afternoon flight to San Francisco, had planned on trying out for an A-League team in the Bay Area this weekend.
