I took a look at rosters in the current NA VCT group and broke down how long each player has been on the team
All players have their term counted from when they first joined the team, NOT from their first match (i.e Guard signed Valyn and neT on November 5, but didn't play an official until November 26).
Any players with a ☆ next to their name were on the roster since the ignition series (First set of NA Valo tournaments)
All days are counted from time of writing (May 19 2022)
