It was appropriate that Martin Rennie should include the coaches when he said everybody had to take responsibility for the Vancouver Whitecaps’ troubling performance in Frisco, Tex., Saturday in a 2-0 loss to FC Dallas.

“Hardly anyone could come away saying they had a good performance,” said the man in charge of a Major League Soccer side now winless in five straight matches.

Sure, the Caps were facing a strong, surging side with the 6-1-1 Texas squad leading the Western Conference. And both Dallas goals — including a Vancouver own goal when a low, one-bounce corner kick caromed off the back of defender Brad Rusin — were the result of convenient bounces.

But FC Dallas, who clearly follow the ‘everything is bigger in Texas’ mantra, did control play much of the night. The Caps, on the other hand, lacked cohesion and organization and were clearly outclassed.

They gave the ball away too easily, runs were misread and the back line was frequently exposed either through a lack of pace or by simply allowing attackers too much room.

“We have to accept that we didn’t play well, that we didn’t turn up,” said dejected captain Nigel Reo-Coker. “Put it behind you and go on.”

The poor play came after some head-scratching decisions from Rennie, whose club now has won just three of its last 18 games dating back to last season. That’s a dismal record by any measure, and has all but wiped away the positive vibe from a 2-0 start to this season.

Rennie, who gave third-choice striker Tommy Heinemann and midfielder Matt Watson their first starts of the season and, strangely, elected to gift rookie Erik Hurtado with another one, didn’t have a single player on the field at the opening whistle who has scored an MLS goal this season.

And the 11 men who started the game had combined for a measly nine career MLS goals, five of them from left fullback Alain Rochat.

Was it any wonder the offensively challenged Caps, now 2-3-2 on the season with just seven goals scored, were shut out?

Kenny Miller (two goals this season, hamstring) and Corey Hertzog (one, concussion) were not available. But Rennie also chose to leave midfielder playmaker Daigo Kobayashi (one) in Vancouver, supposedly to rest, and had Camilo Sanvezzo (one), Darren Mattocks (one) and Gershon Koffie (one) on the bench — again.

The latter three entered the match in the second half, but only after Dallas, taking advantage of poor transition marking by the Caps after a Hurtado corner kick was easily cleared, scored in the 50th minute to make it 2-0.

A Kenny Cooper shot from outside the box glanced off fullback Y.P. Lee and fell to Blaz Perez, who had snuck behind Rusin and Andy O’Brien and whose header easily found net with Caps’ goalkeeper Joe Cannon going the wrong way.

A physical Reo-Coker tried his best in the first half, aggressively winning tackles and taking the ball forward. But there was little chemistry with Watson, Heinemann or the speedy Hurtado, who continues to struggle with a lack of touch on straight ahead runs and poor decision-making.
