The logic just doesn’t hold. You just cant say that a brand new team is going to have the goal of playing nearly 8x better at home thats just not how it works. You are really disrespecting the math significance here. Instead of making excuses for a poorer road performance as you’ve done here, this can be evaluated objectively. What im saying is that the colossal difference in statistical significance between home and away points to outside factors being at play. Making excuses for poor road performance doesn’t work, as by that logic that would mean that thr team would have to play 8x better at home to satisfy it, thats just not realistic.
No doubt, Vegas' environ has the potential to impact players in a negative way moreso than any other in the league, I would say that is fair to suggest for sure.
Plus, the impact that the terrible tragedy in Vegas at the start of the season (and the ensuing Vegas strong feeling) could be at least contributing to Vegas' home record - even if just in a small way.
The impact of these 2 factors though will likely diminish over time. 1) Teams will figure out ways to mitigate the impact of the Vegas environ - stay a shorter time in the city, etc, etc,.
2) As time passes, the tragedy (while heartbreaking) just by sheer fact of it being further in the past, will come to be less of a motivator for the team, if indeed, it has had any positive effect on the team this year.
