Many people associated Bill Parcells with having one of the biggest egos in the entire National Football League. While that may be true, he was one heck of a head coach during his heyday.
In 1983, he took over a New York Giants team that had one winning season in the previous 10 seasons and led them right back to respectability. Following a 3-12 first season with New York, Parcells led them to the playoffs in his second year with the club. They would make it there again in 1965, but without much success.
The 1986 Giants went 14-2 and dominated the rest of the NFL in the regular season. In fact, their two losses came by a combined seven points. Surprisingly, New York killed the San Francisco 49ers 49-3 in the NFC Championship Game to go to their first Super Bowl in club history. They defeated the Denver Broncos 39-20.
New York went back to the Super Bowl in 1990 after a couple sub-par seasons. This time, they took on the Buffalo Bills in their first ever appearance. With the Giants winning 20-19 in the last seconds of the game, Scott Norwood's field goal attempt sailed wide right, and New York was preserved their second Super Bowl title in franchise history, both under Bill Parcells.
Bill Parcells left the Giants in 1990,only to return to coach the New England Patriots in 1993. The Patriots had won a total of 19 games in the five seasons prior to "Tunas" arrival.
Over the course of the next five seasons, the Patriots made the playoffs twice and went to the Super Bowl in 1996, losing to the Green Bay Packers.
Parcells finished out his coaching career with the New York Jets and Dallas Cowboys: without much success.
