I wouldn't say we were that bad on special teams. Our punt and kickoff return coverage was pretty good (besides the preseason game against Tampa which doesn't matter). We have a bunch of good special teamers in Hendricks, McGarrahan, Gamble, etc.
However, returning was a different story. Johnson was doing well when he got injured and when he went down special teams went down as well. Minor was a good returner and that play against New England when the ball didn't go in the endzone was a total fluke and luck for the Patriots.
Our biggest problems on special teams last year were punting and punt returning. We have some good returners in camp this year, and Baker has gained a lot of experience in NFL Europe which should help us. I don't think returning will be a problem this year.
Our biggest problem on special teams will be punting. I think Mare will return to form and we will be fine on field goal situations. What we need is a good punter. Royals isn't a good punter, and it will be a problem all year. I think we have another punter in camp, I surely hope he is better.
