Premier League: who will improve in the second part of the season? Part 2.

In the Part 1I used the shots per goal conceded statistics to figure out which teams may have been (un)lucky in the first 16 games of the season and are expected to improve the defensive record in the remaining games of the season. In this article I will do the same for the offensive side of the game – are there teams that score fewer goals than they should simply because they have been unfortunate?
