When the AFL and NFL merged before the 1970 season, Cleveland became part of the new American Football Conference (AFC). While the Browns made it back to the playoffs in 1971 and 1972, they fell into mediocrity through the mid-1970s. A revival of sorts took place in 1979 and 1980, when quarterback Brian Sipe engineered a series of last-minute wins and the Browns came to be called the "Kardiac Kids". Under Sipe, however, the Browns did not make it past the first round of the playoffs. Quarterback Bernie Kosar, whom the Browns drafted in 1985, led the team to three AFC Championship games in the late 1980s but lost each time to the Denver Broncos.
