With training camp a week away, D.C. United have not landed a high-end scorer and, barring a big move before the March 3 opener, will enter the Major League Soccer season with three forwards who have never scored more than eight goals in one year. The club did obtain one front-line candidate in a trade with the Portland Timbers: Jamaican forward Darren Mattocks. But instead of a major upgrade at that position, coach Ben Olsen said United will rely on Mattocks' athletic skills, a fortified midfield and a collective scoring effort to rebound from last year's last-place finish in the Eastern Conference. "It's always going to be by committee with us," he said during a recent interview. "We design our team in that way and everybody has to help from a goal standpoint. Why? Because David Villa is not on our team." Villa, the Spanish national team's all-time scoring leader, has 63 goals and 21 assists in three seasons for New York City FC. He also earns $5.6 million, five times more than any D.C. player. With Audi Field opening this summer, United have pledged to increase spending after years of thrifty decisions. In the past six months, the club has added six players with national team experience: Mattocks, Bruno Miranda (Bolivia), Paul Arriola (United States), Zoltan Stieber (Hungary), Ulises Segura (Costa Rica) and Junior Moreno (Venezuela). It also traded for David Ousted, one of the league's better goalkeepers, and veteran defender Frederic Brillant. The MLS Players Association will not post salaries until the spring, so it's unclear how much more the organization has committed to the payroll. United remain in the market for depth at wide midfield and outside back, but there's unlikely to be a blockbuster signing before the summer transfer window. They also have the No. 3 overall pick in Friday's MLS draft, but such players are primarily for depth. Asked whether United pursued a high-priced, proven scorer this winter, Olsen said: "Yes. We're always looking, and we will continue to look for, competition up there. It's a vital position, but they are all vital." Mattocks, 27, has scored 24 goals in 136 regular season appearances. His career high was seven in his 2012 rookie season with Vancouver.
