Ultimately that's the stat that matters, but overall have we got what we deserved or been lucky/unlucky? In any particular game you can say 'if only' and although 19 games isn't enough for everything to even itself out, it does start to provide better clues to the longer term performance.
In terms of shots per game, Swansea are actually 18th in the league, although this will in part be due to the amount of time Swansea have spent in front (generally speaking, the team leading takes fewer shots than the team chasing the game - although not necessarily good quality shots).
On a not overly scientific basis, I went through the 19 games and put a 'deserved' score down based on how I felt each match went in terms of shots/game state (i.e., scoring first) and overall performance. This provides an rough estimate of what I thought we were worth in each match, with Liverpool being the lowest and West Brom being the highest.
|No game is ever a 0 or a 3 but somewhere in between|
You could probably pick apart any individual estimate above and everyone would have differing opinions on relative performances but I think the key this season has been beating the 'smaller' teams (along with the wins over Arsenal and Man Utd which were a bonus).
The first half of the season saw Swansea play Home to 5 of the current bottom 6 (all except Hull) which in part explains why Swans are 5th when looking just at home form so starting with QPR on New Years Day the away schedule should arguably get easier but the home one tougher.
