And whatever you mean, it might be reasonable to have a proper title on your thread...
During the season you can invest money into scouting every week (via the menu point "Training-Scouts") and at the end of the season you get to see a list of all possible draftees in which you can amend the order. According to the league's results the draftees are allocated to the teams.
But if you want to know more about the procedure, wait for the playoffs and there'll be around 3957204 threads asking "When is the draft?????" and "How does the draft work????"
We have both said a lot of things that you are going to regret.
