A year ago, the Buccaneers signed punter Bryan Anger in free agency, and that move went so well that Anger got a new multi-year deal at the end of the 2016 season. Tampa Bay was eager to stay with the status quo (which also meant re-signing Robinson, the gunner extraordinaire) after improving from 27th in the league in net punting average in 2015 to third in 2016.
On the other hand, there's no guarantee of maintaining the status quo at the other two specialist spots. Long-snapper Andrew DePaola, who handled the job so well the previous three seasons, suffered a knee injury in the season finale and became a free agent on March 9.
