John Clayton reported today on ESPN’s NFL Live that in the event they are unable to resign him, the Houston Texans will likely use the franchise tag on Mario Williams. This would be a stunning move for a team that played well on defense despite losing Williams in week 5 versus the Oakland Raiders. The Texans finished the season ranked second in total defense, and the sixth in sacks. Williams, selected first overall in the 2006 NFL draft, would count at least $21M against the Texans’ salary cap if the franchise tag is used. The 2-time All Pro looked promising in converting from a defensive end to an outside linebacker in 2011, when the Texans’ new defensive coordinator, Wade Phillips, converted from a 4-3 to a 3-4 defense.
