Seems like he has had a few of these plays . Hopefully many more to come . <| sep |> They do that too . Let ' s take the NFL , for simplicity sake . When you turn pro , you enter the draft . The draft order is such that every team gets a pick in order from worst record the previous season to best . There are 7 rounds of that . When a player is drafted he gets a 3 or 4 year contract , depending on where he was drafted . At the end of that contract , he is a free agent and can sign anywhere he chooses , though teams are only allowed to spend so much money on players per year . Baseball is even weirder . If you ' re American or Canadian , you go into the draft . However , if you are from some other countries , like most of Latin America , you are free to sign with whoever you want when you turn 16 .
