I think this is far more unlikely. The problem with field goal distance is that, even though kickers have greater power and accuracy than ever before, this sort of record depends entirely on very specific game conditions and coaching decisions. Consider that to break the record with just a 65-yard FG, even a good kicker has a low chance of making it even in ideal conditions, even if the ball WOULD go through the goal posts, the distance requires a lower angle meaning greater chance of being blocked. Worst of all, the field position given up in the case of a miss for that would be on giving your opponent the ball on your own 48, essentially mid-field. That’s a big risk with a big drawback.
Further, consider how much pressure coaches are under to win these days. It seems to me that many coaches aren’t even taking what ought to be statistically good risks. Unless you’re one of the few coaches that isn’t potentially on the hot seat following a potentially disappointing season, coaches are less likely to be blamed for making decisions that follow traditional football wisdom rather than something that makes sense with more modern statistical analysis.
As such, you’re really only going to see a coach even attempt a 60+ yard field goal under very specific circumstances. Generally, they need an awesome kicker, they need ideal conditions, the field position needs to fit and they need to have a situation where the risk of a miss is largely mitigated. So this will really only come up if a team is well ahead and they just a few seconds on the clock and happen to be just inside the 50. They can either kneel, take a long bomb, or try a long field goal, with the result of the play ending the half, making the field position risk moot. It’s not going to happen at the end of the game since, generally, a 50-yard TD pass is probably a better chance than a 65-yard FG.
So, I think we might see a handful more 60+ makes in the next several years, but a 70-yard FG in game conditions isn’t something I could see even the most aggressive coach really wanting to put his kicker into, perhaps unless the kicker were really begging for the chance. And I really doubt too many kickers are that worried about it since kicker careers tend to be short lived if they have too many misses.
Then again, who knows, we might see just the right conditions show up next week in the playoffs. I’m far more inclined to see achievements of records based on accumulation of stats or extreme luck. Like, perhaps, a truly perfect 19-0 season (and I thought the Panthers had a decent chance of 16-0 this year), maybe career sacks, or similar types of stats getting broken.
