Which NFL Records Will Never Be Broken?

[Bunk]

I would guess there are many records unlikely to be broken but I can only think on one that absolutely cannot be broken (but could be tied).... the 1972 Dolphins perfect season. You can't beat perfect.

Didn't the Dolphins play 14 games and are the teams now playing 16 games. So wouldn't a 16-0 undefeated regular season record beat the Dolphins' 14-0 record. Even though the winning percentage would be the same, the number of wins would be greater

Here is another record that can not be broken only tied.
Cordarrelle Patterson's 109 yard kickoff return.

Unless they lengthen the field or end zones---haha!

Does anyone have a 109-yard missed FG return?

Auburn U had a player that returned a 109 field goal attempt. I don't know the longest in the NFL.
