The last time a Cubs shortstop reached both 20 HRs and 90 RBIs was Ernie Banks in 1960. He had a very good career.
Addison will never reach the power numbers of Mr. Cub, but Ernie never had the glove that Russell does. They are two different players, but they are both good players.
At just 22 years old, Russell will only get better. I'm looking forward to that.
