Among the Texans' biggest shortcomings last season was a return game that lacked explosiveness.
The Texans are trying to upgrade that area of the special teams, drafting shifty San Jose State running back Tyler Ervin, Notre Dame wide receiver Will Fuller and Ohio State wide receiver Braxton Miller along with adding speedy undrafted free agent Wendall Williams.
Ervin returned three kickoffs for touchdowns in college and is his school's all-time record holder for kickoff return yardage and combined kickoffs and punts returned for scores with five. Williams has 4.32 speed in the 40-yard dash and returned four kickoffs and one punt for touchdowns in two seasons at the University of the Cumberlands.
