These aren't really great reasons, especially 3 and 4. For 1 and 2, I can see that playing into it, in my mind, not great reasons, but can see where the voters would get drawn into the recent performance down the stretch, etc....but on balance of the season, not a big difference.
For 3, that almost highlights MacK's importance, when he went through a slump, the team struggled.
For 4, yeah NJ was bad the year before and had a great turnaround, but CO was in the same boat the year before except worse....had a better turnaround....improved by 47pts vs. NJ improvement of 27pts.
