It's not that simple and this is why it's hard to gauge. Aaron Jones or someone like that is more impactful to a game than any kicker, but if Aaron Jones has a bad game it is unlikely to single-handedly cause a loss. A QB can have that kind of impact but a kicker missing 2 FGs can be devastating. Talk to a Cowboys fan if you think a bad kicker can't be a multi-year disaster that loses multiple games while multiple guys try and fail to win the job. At most of the positions there is someone else to provide some replacement value and you can change the gameplan to mask the loss of what was there. There is no doing that with a reliable kicker, you either make kicks or you don't. Yeah, you might be OK with Gostkowski, but we've all see situations where a kicker is plucked off the WW that week and it leads to a total disaster. That can directly lose a game, which is sometimes all it takes to miss the playoffs. So I don't think K is quite to the level of those most important positions, but I think you're dead wrong that a kicker loss can't derail a season. Especially one as reliable as Mason has been for a while now.
