I think if you're depending on that 3-5 record as being predictive you're in for an unpleasant surprise next season. Every team is injured at the end of the season.
The difference between the worst punter in the NFL and the best is MARGINAL. In fact, I'd say that the difference between the best punter in the NFL and the 10th guy teams call when they need an injury replacement isn't really enough to matter.
The difference between Blake Gillikin, who people are very concerned about losing, and Nolan Cooney, whose name I literally wrote for the first time ever on this board, was 2.6 net yards per punt.
