Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: Seattle has three major men's professional sports teams: the National Football League (NFL)'s Seattle Seahawks, Major League Baseball (MLB)'s Seattle Mariners, and Major League Soccer (MLS)'s Seattle Sounders FC. Other professional sports teams include the Women's National Basketball Association (WNBA)'s Seattle Storm, who won the WNBA championship on three occasions in 2004 and 2010, and 2018; and the Seattle Reign of the National Women's Soccer League.The Seattle Seahawks entered the National Football League in 1976 as an expansion team and have advanced to the Super Bowl three times: 2005, 2013 and 2014. The team played in the Kingdome until it was imploded in 2000 and moved into Qwest Field (now CenturyLink Field) at the same site in 2003. The Seahawks lost Super Bowl XL in 2005 to the Pittsburgh Steelers in Detroit, but won Super Bowl XLVIII in 2013 by defeating the Denver Broncos 43–8 at MetLife Stadium. The team advanced to the Super Bowl the following year, but lost to the New England Patriots in Super Bowl XLIX on a last-minute play. Seahawks fans have set stadium noise records on several occasions and are collectively known as the "12th Man".Seattle Sounders FC has played in Major League Soccer since 2009, sharing CenturyLink Field with the Seahawks, as a continuation of earlier teams in the lower divisions of American soccer. The team set various attendance records in its first few seasons, averaging over 43,000 per match and placing themselves among the top 30 teams internationally. The Sounders have won the MLS Supporters' Shield in 2014 and the Lamar Hunt U.S. Open Cup on four occasions: 2009, 2010, 2011, and 2014. The Sounders won their first MLS Cup after defeating Toronto FC 5–4 in a penalty shootout, in MLS Cup 2016; the team would go on to finish as runners-up to Toronto FC in the following cup. CenturyLink Field hosted the 2009 MLS Cup, played between Real Salt Lake and the Los Angeles Galaxy in front of 46,011 spectators.Seattle also has a Major League Rugby team, the Seattle Seawolves, who play at Starfire Sports in Tukwila, a small stadium that is also used by the Sounders for their U.S. Open Cup matches. The team began play in 2018 and won the league's inaugural championship. Seattle will also host a new XFL franchise that will begin play in 2020 at CenturyLink Field.Seattle's professional sports history began at the start of the 20th century with the PCHA's Seattle Metropolitans, which in 1917 became the first American hockey team to win the Stanley Cup.
What year will the XFL franchise in the city that has three major men's sports teams begin play?
