The last four NFL expansion teams are the Jacksonville Jaguars, Carolina Panthers, Houston Texans, and the most recent team, the Los Angeles Rams.
The Jacksonville Jaguars were founded in 1993. Their first season was 1995. They played their home games at EverBank Field. The team has made it to the playoffs eight times since they started playing and their best season was 2017 when they made it to the AFC Championship game.
The Carolina Panthers began playing in 1995 as well. Their home games are played at Bank of America Stadium. The team has won six division championships and have made it to the playoffs eleven times total. Their appearance in Super Bowl 50 was their only appearance in a Super Bowl thus far.
Houston Texans joined the NFL in 2002 as an expansion franchise after Houston’s previous franchise, the Houston Oilers, relocated to Nashville and became the Tennessee Titans. The Texans play their home games at NRG Stadium and have won four division championships since joining the league. They have also made seven playoff appearances with their most recent being in 2019 when they lost to Kansas City Chiefs in overtime of the AFC Divisional Round playoff game.
Finally, Los Angeles Rams became an expansion franchise for a second time when they moved back to Los Angeles from St Louis in 2016 (they were originally located in LA from 1946 until 1994 before moving to St Louis). They play their home games at SoFi Stadium which opened this year (2020) and cost approximately $5 billion dollars to build making it one of the most expensive stadiums ever built. In just three seasons back in LA, the Rams have already won a division championship (2017) and made two playoff appearances (2017-2018).
