Gentlemen, start your legal tampering.
The NFL official tampering period began at 11 a.m. in advance of Wednesday's official start of the free agent signing period.
The Texans will spend this time negotiating with their own unrestricted free agents, including highly regarded offensive guard Brandon Brooks and center Ben Jones.
They'll also take the temperature of free agents like Denver Broncos quarterback Brock Osweiler, Tampa Bay Buccaneers running back Doug Martin, Miami Dolphins running back Lamar Miller and New York Jets running back Chris Ivory, among others.
The Texans could also use reinforcements at safety, wide receiver and defensive end.
