Because after a really great start, he's REALLY cooled off. Fisher went from specifically setting up long FG's for scoring opportunities to almost completely not even attempting them so the numbers are even more skewed than they appear. He went from being a potential weapon from long range to a guy that needed to be protected from himself. IMO of course.
Punts from the oppositions half last season:
49ers 44 yard line, passed up a 61 yard FG attempt.
Titans 43 yard line, passed up a 60 yard FG attempt.
Saints 45 yard line, passed up a 62 yard FG attempts.
We also went for it on 4th down in opposition territory with the game close and not late in the 4th Q once, going with a fake punt rather than a 55 yard FG.
Maybe those 3 we would have attempted in Greg's first few games, can we say 100% that the reason we didn't was to protect him from himself? Or that we would if we had more trust in our kicker?
