Media Day is the NHL's equivalent of yearbook photo day taken to the next level, with all sorts of photos and video being taken of the players. Most significantly, the players take their media mugshots that will be used everywhere by everyone for the next year, from the official NHL site to next year's edition of the EA Sports NHL 18 franchise.

The mugshots are also a great way to see how the players have evolved over the years, from their first season with the big club to their current status as a grizzled (sometimes literally) veteran.

In honor of that evolution, sjsharks.com took a look at the mugshots of some of the longest-tenured Sharks players to see how they've changed their look over the years.

Note: Despite evidence to the contrary, we swear there isn't a reverse-Yankees facial hair requirement on the San Jose Sharks. At least, we don't think there is.
