Going into 2015, what MLS team had won 2 MLS Cups but never won a Supporters' Shield?

Going into the 2015 MLS season, the Houston Dynamo had won two MLS Cups but had never won the Supporters' Shield. Houston captured back-to-back league championships in 2006 and 2007, yet never finished an MLS regular season with the league's best record during that period.

The distinction matters because the MLS Cup and Supporters' Shield reward different achievements. The MLS Cup is awarded after the postseason playoffs, while the Supporters' Shield goes to the team with the most regular-season points. A club can therefore win one trophy without winning the other. Houston reached the MLS Cup final again in 2011 and 2012, losing to the Los Angeles Galaxy on both occasions.

The Dynamo's early success was closely tied to coach Dominic Kinnear and players such as Brian Ching, Dwayne De Rosario and Brad Davis. The franchise had inherited the competitive legacy of the San Jose Earthquakes before beginning play in Houston in 2006. That history helps explain how the Dynamo won two titles immediately, while the Supporters' Shield remained absent from their honors list. The club later won the 2018 U.S. Open Cup, but not the Shield.
