Nervous Ned?

I'm sure most everybody has already read John Donovan's piece on SI.com about Yost being the man Brewers fans love to hate. But in case you didn't here's the quote that most caught my attention:

A couple of his former players have called the manager "Nervous Ned," remarking how he gets uptight in pressure situations late in the season or in close games.

I'd never heard this before and was instantly thinking I hope that some writers or reporters in the "real" media get in touch with more of Ned's former players to see what they have to say about him as a manager.
