Chicago Cubs' pitching depth is a never ending cause of concern.

"You can never have too much pitching," somebody once said.

"You can never have too much hitting," said Dale Sveum.
"Or prospects." said Theo Epstein and Jed Hoyer simultaneously.
To which Starlin Castro's hamstring replied, "You can never have too many shortstops either."
"You can never have too many third basemen," said Gary Scott, along with the couple hundred Cubs third basemen since Ron Santo retired.
"What about phenoms?" asked Felix Pie. "You can never have too many phenoms."
"Calluses are important," added Moises Alou. "You can't have too many calluses on your hands, which is why I used to pee..."
"Stop right there, please."
It was George Brett, obviously in the wrong room.
"It's actually pine tar - you can never have too much pine tar," he said.
You are correct, sir, I thought.
Then: "We think you can't have enough left tackles," said every Bears fan in the world.
Who could argue with that many loud people?
And while my ears were still ringing, I thought I heard someone say, "Or Crane Kenneys. You can NEVER have enough Crane Kenneys."
But I was wrong, because nobody said that.
Ever.
Then it was quiet again for a couple minutes before I heard Albert Einstein say, "No, it's definitely pitching. You can never have too much pitching."
And I thought about the Cubs. And Matt Garza's lat. And about Scott Baker's Tommy John. And I even thought about Thomas Diamond and Doug Davis and Scott Maine.

And then I thought man, that Albert Einstein is one smart dude.
