People should probably realize comparing Espinosa's down year to Desmond's down years reallt isn't fair. Danny is so much better than bad Ian ever was.
He really doesn't have to improve much.
Hell, if he stayed the same he's still a power threat with good speed and gold glove quality defense.
The comparisons to Desmond of the past isn't fair to Danny. Desmond was one of the three worst SS's in the game. Danny's already a first division 2B.
