The Cowboys had one of the best special teams units last season, when they didn't have to kick field goals.
There should be a lot of changes in the return game because of the draft, and in the kicking game. The only position that's solidified is punter so we'll start with that.
The Cowboys didn't allow a kickoff TD last season and just one punt return for a TD. Patrick Crayton had two punt returns for TD's but he's expected to lose his job.
The only sore spot was field goals. Nick Folk lost all his confidence last season after having two terrific years and was cut. Shaun Suisham was signed but he wasn't any better and was cut at the end of the season.
