Difference is:
a) Much more relevanty footy content in the AFL version, too much BS segments in the NRL
b) a better balance of straight panellists (Lyon, prettyboy Brayshaw) and the comic relief (Newman). Meanwhile in the NRL it seems like every bloody host is trying to be funny 24/7 and noone tries to be serious for even part of the show. It's been like that since they got rid of Sterlo.
c) the AFL show is just run so much more tightly. They go from segment to segment, from topic to topic, without as many interruptions and they don't let themselves get sidetracked too far. If Newman gets too carried away Lyon/Brayshaw always pull him back into line. While the NRL one is nothing like that. They spend ages doing injokes only they think is funny (segments on Marios stupidity, Brohmans obesity etc etc). They run out of puff every 15 mins.
Channel 9 should get whoever is the producer of the AFL version to spend a season on the NRL version and it would be so much better.
