Grimes appeared in 14 games for the Texans and rushed for 282 yards as Houston's third option behind Alfred Blue and Chris Polk after Arian Foster missed 12 games due to injury last season.
Grimes will be returning to an offense that has undergone some big changes already this offseason. On March 3, the Texans released their franchise rushing leader in Foster after injuries continually left Houston in a bind.
Over the past three seasons, Foster missed 23 games and the Texans were forced to roll out second-tier backs like Ben Tate in 2013 along with Polk and Blue last year.
In 2015, Polk and Blue combined for 1,042 yards, but averaged just 3.6 yards per carry. Grimes on the other hand averaged 5.0 yards per rush on 56 attempts.
Miller will get his wish in Houston as he'll be supported by the likes of Grimes, Blue and Akeem Hunt, who attempted only 17 rushes last season. Polk on the other hand remains a free agent and is now expendable with Grimes' signing.
It's unlikely that Grimes will see much of a bump in carries with the arrival of Miller and with Blue still in front of him. But if the injury bug bites the Texans like it did to Foster, Grimes' presence is crucial to Houston's depth in an offense that is now headed by former Denver Bronco and Peyton Manning backup Brock Osweiler.
