Who is the definate #1 CB in the Draft?

There isn't a definite #1 CB, and the Saints might not be the first team to pick a CB.

Anyway, I like Leodis McKelvin the most. He's fast and quick, great in coverage. He's a decent tackler and a great returner. Not a big guy, but he can jam receivers. He compares to Lito Sheppard or Dunta Robinson.
