Minnesota United's rise from two losing seasons to the verge of the playoffs has included its heights and depths.
The U.S. Open Cup finalist won 2-0 at Western Conference-leading LAFC three weeks ago and delivered a needed 3-1 home victory over Real Salt Lake last weekend. It also has lost at slumping Houston, Sporting Kansas City and Colorado, among others, and tied Vancouver and Orlando City at home.
Is the disparity simply a team newly assembled this season learning to play together?
"No, that's a team not being prepared to play on the night," United coach Adrian Heath said. "This group can play. We know that."
United has played well enough despite lost opportunities to clinch its first playoff spot on Sunday with a victory at Portland, thanks to Atlanta's victory over San Jose on Saturday.
Player absences and changing lineups and formations might have contributed to those lost opportunities. But Heath notes that even Tottenham Hotspur coach Mauricio Pochettino in England's Premier League wonders why a team that finished runner-up in last season's UEFA Champions League is winless in its past nine league road games.
"I don't know, Pochettino doesn't know," Heath said. "You don't know sometimes. You think you know what the reasoning is, but we're human beings. The players are human beings. You have games when it's good. You have games when it's not so good."
By adding five starters over the winter and another three players during a summer transfer window, United has improved enough to have not only a playoff spot in sight but one with home-field advantage. Starting with a match at Portland on Sunday, it has four regular-season games left.
