It's always important to adjust for era. There are 30 pages of Ken Griffey, Jr. highlights on MLB.com. There are 20 pages of Bryce Harper highlights on MLB.com. So has Bryce Harper already accomplished two-thirds as much as Griffey? No, of course not. Maybe half. But not two-thirds.
Still, there are 20 pages of Bryce Harper highlights on MLB.com. And, like the old expression goes, they can't all be walk-off singles.
No matter where he is in the house, when the phone rings Bryce Harper always wants to answer it.
