Do the Houston Texans have a problem at running back?

For the third preseason game of the Houston Texans’ preseason Saturday night, where the Texans defeated the Denver Broncos, 18-17, at least one question remained.

The question, more importantly than a win in a preseason game, is do the Texans have a problem at the running back position?

With starting running Arian Foster still not playing in a preseason game after three weeks (he missed all of the 2013 preseason), the Texans looked to four different running backs to carry the ball on Saturday, none rushing for over 30 yards.

Leading the Texans in rushing was rookie Alfred Blue with nine carries for 27 yards, followed by Jonathan Grimes with five carries for 22 yards.

Ronnie Brown followed with four carries for 19 yards, and William Powell having three carries for six yards.

Quarterback Ryan Fitzpatrick also had six yards on one rush, and third string QB Tom Savage having one rush for -1 yard.

But looking at the current backs on the Texans roster, I don’t know about you, but if Foster isn’t able to stay healthy this season just like last season where he missed eight games, where will the Texans look to?

The insurance policy of having Ben Tate waiting in the wings in case of an injury is no longer an option, and to be honest the Texans don’t have much in terms of running backs in the reserve role … it seems.
