The statistics in the first table in this article is so telling.

The stats tell nothing except what you want them to tell.
I could interpret it the following ways as well:
1) From the season starting 2010 to 2013, we wasted respectively 278, 275, 280, 231 chances. My god, SAF's and Moyes' attack were so wasteful compared to LVG's who only wasted 238 and 179. In the second season, LVG's team wasted 59 less chances, that's a 24.8% improvement.
2) Out of total shots, shots on target were 24.5%, 27.12% 26.64%, 26.88%. LVG's first season was 24.43% but second was 26.63% which is higher than the average of 26.16% of the first 3 seasons in that table which were under SAF. Woohoo... LVG's team not only improved from his first season but also managed to edge SAF!!!!!!
3) How about goals as a percentage of total shots? From season starting 2010 to 2013, the stats are 9.15%, 10.13% and 10.54% and 8.70% respectively. LVG's last season was 9.16% and currently it stands at 10.05% Woohoo... another improvement and manages once again to edge out SAF's three-year average of 9.94%!!!!
4) Maybe we can move on next to goals per shots on target? The stats are then 37.33%, 37.35%, 39.29%, 32.35%. LVG's seasons are 37.5% and 37.74% respectively. Based on this, it implies LVG's has only "failed" to match the 2012 season under SAF. He's beaten all the rest of the seasons in that table.
So the stats above conclude that:
a) SAF's team did create the most chances, but the strike force was so inept it has wasted so many more chances. If they were as well-coach as LVG's team, then they would have scored more goals.
b) LVG had a slow start but his strikers have progressively gotten more accurate because the ratio of shots on target to total shots have improved.
c) Another one: LVG's team is better coached because it scores more goals compared to shots taken (much less wasteful)
d) Better strike force surely? LVG's strikers convert a higher percentage of shots on targets into goals on average.
e) However you splice it, Moyes is shit. His team wastes the most shots (280), has the poorest goals as a total of shots taken (8.7%), converts the least percentage of shots on target (32.35%) and of course finished 7th... lowest so far.
I wonder what the defensive stats are?
So what ARE the stats telling? Not much...
