Ninja of the day, or of the race isn't entirely about numbers, it's about the whole "WTF?!?! How did he get there? I've seen him maybe 3 times this week."

It's an art, not a science. Zubeldia had it perfect, he wouldn't be on the front of the lead group but not yoyo-ing off the back like a Meintjes, or Leipheimer before him. Kloden wasn't bad either.

This is why the Ninja of the TDF so far is either Uran or Mas for me.
