Best of 2017 in sports

2017 opened with the best College Football Playoff National Championship to date and only got better from there.

Although the year as a whole will be looked back on as a time of strife and upheaval, 2017 provided more than a few indelible moments in sports history. A month after Clemson's stunning, last-second win over Alabama for the FBS college football championship, the New England Patriots capped the biggest comeback in Super Bowl history to claim their fifth NFL Championship in a 34-28 overtime victory over the Atlanta Falcons.

The close finishes continued in the climax of the NCAA Men's Basketball tournament, where the North Carolina Tar Heels defeated the Gonzaga Bulldogs after trailing with less than two minutes to go. On the NCAA Women's side, basketball fans witnessed one of the most shocking upsets ever when the heavily-favored UConn Huskies lost in the semifinals to Mississippi State on a buzzer beater to end their 111-game winning streak (the Bulldogs lost to the South Carolina Gamecocks in the National Championship Game).

The Pittsburgh Penguins claimed their second straight Stanley Cup with a win over the Nashville Predators in six games, while the Golden State Warriors, lead by Kevin Durant, won their second title in three years by defeating LeBron James and the Cleveland Cavaliers in a "three-match" of the past two NBA Finals.
