"The money quote, from Jason Giambi, is right there on the cover of Sports Illustrated, like a fastball under Alex Rodriguez's chin.

'Alex doesn't know who he is,' Giambi says of A-Rod, the SI cover boy. 'We're going to find out who he is in the next couple of months.'

Here's something we need to find out first:

Who is Jason Giambi to be saying something like that about Rodriguez?"

Who is Mike Lupica to talk smack about Jason Giambi?

Who is Mike Lupica to make fun of Johnny Damon's hair?

Who is Mike Lupica to tell Serena Williams that she ought to pay more attention to tennis?

Who is Mike Lupica to think he's Alex Rodriguez's psychologist?

Who is Mike Lupica to tell Alex Rodriguez that he shouldn't sunbathe in Central Park?:

"Now A-Rod needs to stop talking, too. He needs to stop telling us how smart he is and how good-looking he is. If he really thinks that one of the reasons people don't love him is because he's 'biracial,' as he suggests to SI's Tom Verducci, then it is worth wondering if maybe he got sunstroke that day in Central Park when he became the photo-op heard round the world. ... He also seems to be as insecure as any great athlete you will come across in any sport. He desperately needs to be loved and has put himself in a situation here where he stands right next to a guy - Jeter - who will always be loved 100 times more at Yankee Stadium. That's on Rodriguez. ... Rodriguez needs to stop analyzing himself or begging to be analyzed by sports writers."

I'll answer Lupica's question: Who is Jason Giambi to be saying something about Alex Rodriguez?

At least Giambi is ARod's teammate.

At least Jason Giambi has worn pinstripes.

Who the heck is Mike Lupica?

Jason Giambi is more of a True Yankee than Mike Lupica will ever be. For that matter, Wil Nieves is more of a True Yankee than Mike Lupica will ever be.
