Dolphins sign C.J. Anderson to offer sheet; Broncos have 5-days to match

The Miami Dolphins have made a move to fill a vacancy in the running back group left when starter Lamar Miller signed with the Houston Texans in free agency this week. According to ESPN's Adam Schefter, the Dolphins have officially signed restricted free-agent running back C.J. Anderson to a offer sheet. Anderson's former team, the Denver Broncos, now have five days to either match the offer or allow Anderson to join the Dolphins.

There is no draft pick compensation tied to Anderson's restricted free agent tender.

Schefter reports that the Dolphins' offer sheet to Anderson is a four-year contract worth $18 million.

Anderson joined the Broncos as an undrafted free agent in 2013. Dolphins head coach Adam Gase, who was the offensive coordinator with the Chicago Bears last year, served as Denver's offensive coordinator in 2013 and 2014, giving him first-hand understanding of Anderson's game, and providing Anderson with an understanding of the offense Miami should run in 2016.

Anderson only say playing time in five games as a rookie, with seven carries for 38 yards. In 2014, Anderson played in 15 games, with 7 starts, and carried the ball 179 times for 849 yards with 8 touchdowns. Last season, Anderson struggled early in the season as the Broncos' offensive line dealt with injuries, but came on strong in the second half of the season and finished the year with 152 carries for 720 yards and 5 touchdowns. He also caught 25 passes for 183 yards.

In the playoffs, Anderson carried the ball 54 times for 234 yards and two touchdowns, along with 9 receptions for 39 yards. That includes a 90-yard, one-touchdown performance in Super Bowl 50.
