SNF
SNF is short for Sunday Night Football currently aired on NBC. It's another money guzzler thing the major American football broadcasting companies are pulling.
I watched SNF as my final gasp before the work week started again but it was one hell of a Sunday finale; Cowboys-Eagles at 1, Giants-49ers at 4, Colts-Pats on SNF at 7 and Packers-Bears on MNF.
