The dramatic turnaround of the Houston Astros franchise from historically bad -- they were the second team in MLB history to have three consecutive seasons of at least 106 losses -- to world champions in just five years has been fueled by the development of an All-Star lineup with marquee names such as George Springer, José Altuve, Alex Bregman and Carlos Correa.
However, while those players are game-changers, having star players alone doesn't guarantee winning it all -- just ask Bryce Harper and the Washington Nationals.
