I think you can get the NFL Sunday Ticket through your PS3 even if you don't subscribe to DirecTV (I think it may cost $100 or so more than the DirecTV Sunday Ticket package, though). It's an alternate option for folks who live in apartment buildings (or in house surrounded by tons of tall trees and such) and cannot mount a dish, but want Sunday Ticket anyway.
The Rams' offense featuring weapons such as Marshall Faulk, Torrey Holt, and Isaac Bruce were known as "The Greatest Show on Turf"
The Steelers' offense featuring weapons such as Le'Veon Bell and Martavis Bryant should be known as "The Greatest Show on Grass"
