those 2 statements kind of contradict each other, and I'm not having a go at you, just saying that if there are any stats that can tell us the likelihood of SM getting promotion this season, then they have to take into account all the dynamic variables - all the differences between the data points, like what players he can pick, and how fit they are for eg.
Comparing SM with what Nolan did with his squad a few years ago is a poor indicator of what SM will do with his squad this season, imo, so what use is a flat comparison?
