Tried Rusty's idea this morning by reinstalling the "failed" leading plugs.  They worked perfectly.  (perfect is a relative term:0) 
I am really baffled as to what caused the false positive that the coil was defective.
Any ideas out there?

The real test would be to put the plugs back in, and see if it still fails.  I would be worried that there was a broken wire going to the coil.  I'm not familiar with the second gen coils, but I assume there's power, or ground, or something that can take out the coil.  I would run it briefly as is, and make sure it's still OK, then put the plugs you just took out in, and run it again.  I would make every effort not to touch any wiring other than the plug wires.  If that's bad, I would put the new plugs back in, and try again, still without touching any other wires.  That test will give you a pretty good idea if it's really the plugs.  
 
It does seem hard to believe that the plugs could both be bad, unless maybe they missed you, and died of loneliness :-)
