Donovan McNabb has the worst TD% of his career and the worst INT% of his career. His completion percentage is where it's always been. The reason his QB rating is down has nothing to do with his completion percentage.

If you use completion percentage, you know exactly what you are seeing. Percentage of completions over total attempts. That's easy. If you use passer rating, you have a gross performance estimate, but you have no idea what you are actually judging a QB on.

In short, completion percentage = good, while passer rating = largely useless.
