That's a good point though - a lot of times the backup kicker or punter on an NFL roster is someone from a totally different skill position.

Ndamukong Suh is a 300 pound defensive tackle but he was the emergency placekicker for the Dolphins for 2017. There are a bunch of QBs who can punt as well.

It's not common for those backups to actually kick, but it does happen. Wes Welker was placekicker for the Dolphins for one game as a rookie in 2004, besides being the team's kick and punt returner. He successfully converted both kicks he attempted. He did not catch a pass in that game, despite being nominally a wide receiver (and a future Pro Bowler at that position). Six years later, at New England, he served as the backup placekicker again and made a single extra point, finishing his career perfect as a kicker.

The legendary quarterback Doug Flutie kicked the last successful "drop kick" in the NFL for an extra point in 2006. However, that was more of a novelty than out of necessity; New England's kicker was healthy, they were well ahead in the game, and the team knew Flutie would retire after the season.
