When you dug them up, did they have eyes?

yes, they sure did. One of them has a little stick of growth up, but it has looked the same for about a week. No change.

Stubborn things !!

Well, if they have eyes , are not mushy or stinky, nor dried out, that about covers it.
Anyone else have any wisdom to share about this?

I find that sometimes dahlias are like petulant children. They will come up when they are good and ready. Often the ones that come up later, come on gangbusters when the sun gets warmer, and the light suits their needs, and they often become the stronger plants. Not always though, but often.

I agree with Grannymarsh. All the basics seem to be in good condition, so wait and see.
