Well, funny how those things work.
For all the talk of chemistry, harmony and camaraderie, Byrd showed in the first inning in Atlanta on Monday how this upgrade could work by blasting a three-run homer against Derek Lowe.
And that's the bottom line: Forget the chemistry talk. If Byrd hits -- something Bradley didn't do last summer in Wrigley Field -- then it will be a huge upgrade.
If he doesn't, it won't matter if the Cubs' clubhouse is a happier place. Bottom line.
Meantime, Byrd becomes the first man to homer in his first at-bat as a Cub since Henry Rodriguez against Florida's Livan Hernandez on March 31, 1998.
I have a feeling he's won over Cubs fans already.
