Collin Klein will play quarterback in Houston, but it will be an uphill battle to make the team.

The Texans were among the busiest teams after the 2013 NFL Draft, signing 23 undrafted free agents including quarterback Collin Klein.

Scouts have suggested that Collin Klein will need to change positions to make his mark in the NFL, but the former Heisman Trophy candidate is determined be a quarterback at the next level.
