Not Telling
Haha! Did you have the same issue or are just saluting me for figuring it out? It may seem trivial but when you're in the middle of a port that took 3 days to compile and run without errors it's hard to zero in. Hoping this post helps someone out in the future!

SOLVED:
If anyone else is having this problem ... you want to make sure you see the viewport outline in pix. The vertex values after transforms were correct in taht they should be displayed on screen. But the viewport structure itself wasn't properly setup (D3D11_VIEWPORT and RSSetViewports) it was set to 0 pixels X 0 pixels due to the fact that setting up the backbuffer is somewhat of a special case because you have to grab it from the swap chain.
Thanks.

Wait a minute isn't there supposed to be a rectangle in PIX representing the viewport?
I guess that means I'm way off!

- I'm clearing the backbuffer to a different color every frame and that is properly flickering
- PIX shows that there is output to the viewport as you can see in the image
- None the less it appears no pixels are being written to the backbuffer
Any ideas? Thanks!

Solved:
There is a way to calculate the proper scale and offset directly form your cascade shadow viewproj matricies. It's right in the article but wasn't working due to a bug in my matrix inversion code.
The way to get the scale remains
The offset is calculated as

The way to get the scale remains
float scale[n] = splitRadius[0] / splitRadius[n]
The offset is calculated as
float4 offset[n] = float4(0.0f,0.0f,0.0f,1.0f) * Inverse(
ShadowMat[n]) *
ShadowMat[0];
