Bad loop

Loop.scala

      if(players.isEmpty) {
        teams
      } else {
        val team = teams.head
        val player = choosePlayer(players)
        team.copy(players = team.players + player)
        val movedLast = teams.tail :+ team
        if(pick % numberOfTeams == 0) {
          cyclic(players.filterNot(_ == player), movedLast.reverse, pick + 1)
        } else {
          cyclic(players.filterNot(_ == player), movedLast, pick + 1)
        }
      }
    }
