Based just on players with Wikipedia pages, the smallest overlap we have with one club in the 92 is Sutton with just three: Jamie Mackie, Simon Walton and
Joshua Johnson (conceded 13 goals in 7 appearances for Argyle, including letting in 6 at West Ham). Harrogate Town is next with 4, then Salford City and Accrington Stanley both with 8. Obviously that's in all teams' entire history, not just counting current players.
The most overlap we have with one club is obviously Exeter due to the proximity, with 79 (and I'm sure a lot more players who aren't notable enough for a Wikipedia page), next after that is Bristol Rovers with 67.
