This season has seen a lot of teams have ups and downs, I don't think many have been super consistent throughout the year.
The cat's had a pretty easy start to the season IMO which set them up well. Plenty of games that they should have won and didn't and probably a few they got away with.
Both top teams only getting 15 wins for the season is a few off past years. If it was last year, 15 wins or 62 points would only just snuck you in to the top 8.
But that said, finishing up the top doesn't always make it an easy run home. Sure, you get a double chance but west coast finishing 8th have an easier run than the cats finishing 2nd.
