In an expected move, the Rams have exercised the fifth-year options for both running back Todd Gurley and cornerback Marcus Peters.

Both players were first-round picks in the 2015 NFL Draft, and are now under contract with the Rams through the 2019 season.

Selected at No. 10 overall, Gurley has been a mainstay of the Rams offense since he was drafted. He's recorded 4,599 yards from scrimmage and 35 total touchdowns in his three seasons as a pro. Gurley was named the AP Offensive Rookie of the Year after rushing for 1,106 yards and 10 touchdowns in just 13 games — a year after tearing his ACL at Georgia. Gurley also earned 2017 AP Offensive Player of the Year by leading the league with 2,093 yards from scrimmage, 19 total touchdowns, and 13 rushing touchdowns.

Since Peters entered the league as the Chiefs 18th overall pick, no player has recorded more interceptions. The cornerback has 19 regular-season picks and two more postseason interceptions — giving him five more than the next player on the list. Peters was named 2015 AP Defensive Rookie of the Year after leading the league with eight interceptions — two of which he returned for touchdowns. He's also recorded five forced fumbles and five fumble recoveries in his young career.

Los Angeles officially acquired Peters at the start of the league year in March.

Since the league's latest Collective Bargaining Agreement in 2011, teams have been able to exercise fifth-year options on the contracts of first-round picks. All contracts of draftees are for four years.
