During the next few weeks we'll take a look at the Houston Texans' pending free agents. Check out the whole series here.
Running back Chris Polk
How he became a Texan: Polk was signed to a one-year deal worth $760,000 last offseason after asking the Eagles to rescind the restricted free agent tender they extended him.
2015 numbers: In 15 games Polk had 99 carries for 334 yards and 16 catches for 109 yards.
Why he might be back: Polk gave the Texans a pop at times.
