It is yes about 2,300 pages with this tag on. I think each page we want to keep, it may need a cleanup but there worth keeping? It's mainly the squad pages, which when i remove the Import tag i am also making sure it has the teams squad seasons template... Saves adding it later!
Hey, I've already been working on a special hub/page for UEFA Euro 2016 (qualification). I've got several ideas. But because it's a lot work I'd like it to know if you like it as well. I've made this to show a little bit the idea so far: Template:UEFA Euro 2016 Hub Boxes. But more will come soon if you like it!
