Cutting the cable, lets talk options and media setups

I am a bit versed with the backdoor solutions ;)
I am mainly concerned with live sports, getting/slinging kids channels to their bedrooms, keeping up with current network shows or DVR options for things like Modern Family that I pick up on the attic antenna.

I guess mostly which other hardware solutions are best to go along with an XBone, home NAS, iMac setup.
