Texans add more speed with San Jose State RB Tyler Ervin in Round 4

The Houston Texans remained on message with their fourth-round pick, taking another fast offensive player in Tyler Ervin out of San Jose State. Every one of their four draft picks so far have been on offense.

My take: The results of the Texans' self evaluation are abundantly clear. They felt they weren't fast enough and set to work fixing that. Every skill player the Texans have taken in this year's draft has one thing in common -- they're all fast. Ervin ran a 4.41 40-yard dash at the combine. He's also got athletic ability beyond that. His 39-inch vertical ranked second among running backs at the combine and his 10-foot, 10-inch broad jump also ranked second among combine running backs.

Running back run: During the height of the Arian Foster era, the Texans never spent draft picks on running backs. From 2009 through 2013, the Texans drafted exactly zero running backs. That's all changed lately. Not only has Houston drafted running backs in each of the past two drafts, they also added high-profile free-agent running back Lamar Miller in March. Miller, like all the skill players the Texans drafted, is fast.
