"My team" as in "The team I'm supporting"
I went to a LAN back in 2011 and VeryGames were there playing CS:S (I know, irreverent game.. but not for this point)
I supported them there, not knowing that they were French until much later.
The core of that team have since become the core of G2 (NBK, Shox, SmithZz (Coach))
Now I follow the team that shox plays for
So they are "My team"
