https://projects.fivethirtyeight.com/soccer-predictions/league-one/ The model is looking very curious right now. Are we king makers or have we just played our toughest opposition?
I'd agree that last season the points at the top of the league were higher than usual but logically that just means the lower teams in the league weren't as strong as they normally are. 2 points a game will win promotion in most leagues, probably by a handful of points. Anything less than 2 points per game and it may or may not be enough.
