With reports that Bob Ligashesky is with Bill O'Brien in Mobile for the Senior Bowl, it would appear that Ligashesky will be retained as special teams coordinator for your Houston Texans. If true, Ligashesky would join Bill Kollar as the only holdovers from Gary Kubiak's staff.
Ligashesky's last non-Texans stint as a special teams coordinator came in Tampa Bay during Greg Schiano's first year as a head coach. Ligashesky's unit finished a dismal 27th by Football Outsiders' DVOA metric. That being said, Joe Marciano's 2012 special teams unit ended the year at 32nd, so I guess we can consider this an upgrade...sort of.
One silver lining to the Buccaneers' 2012 special teams woes were their league leading four blocked punts, which was twice as many as the next closest team. Whether such aggressiveness in trying to flip field position will make its way to Houston remains to be seen. As long as Keshawn Martin stops forcing drives to start at the eight yard line, I will be happy.
