The first area I've looked at is the performance of the top scoring player at each club last season, ranging from 30 goal Robin van Persie down to Franco Di Santo who was Wigan's top scorer with 7 goals.
Taking penalties in to account changes the picture slightly:
Of course not all teams are equal and there are probably plenty of people who think they could score goals if they were playing up front for Man Utd every week given the number of chances created, so the next step is to take shots and chances in to consideration:
Much has been made of Suarez's finishing ability and in terms of shots per goal, his figures are the worst of those above. Also interesting to see that even excluding penalties, Yakubu still has one of the best shots per goal figures.
One thing both Yakubu and Jelavic have in common is that watching them score you get the feeling they are 'lucky' players often scoring relatively simple goals. In reality the skill is in making it look easy and being in the right place at the right time.
Not all chances are equal, a shot could be a 3 metre tap in or a speculative shot at an angle from distance with numerous players in the way. One way Opta have attempted to add a subjective layer to activity is the 'Big Chance' metric. This is defined by Opta as:
'A situation where a player should reasonably be expected to score usually in a one-on-one situation or from close range'
Unfortunately within the data it's not possible to know if that big chance was scored or not, but we can look at the number of big chances and goals each of the players had:
I would also expect that a penalty is classed as a 'big chance' so could possibly get removed from the above to make comparisons fairer.
It's interesting to see Klasnic of Bolton at the top despite having relative few big chances. After an excellent start to the season scoring in each of the first 3 games, missed a couple of games due to suspension and for whatever reason doesn't appeared to have been called on much towards the end of the season. Klasnic played in all of the last 11 league games for Bolton but didn't play the full 90 minutes in any and only 300 minutes in total during those 11 games.
For the three players highlighted in the figures above, over 40% of their shots were classed as big chances (this is a simplification as some big chances may not result in a shot e.g., player delays too long and defender comes back to tackle).
Almost half of Darren Bent's shots are big chances, Bent along with Danny Graham at Swansea have the lowest number of touches per game with 28 (compared to Fletcher with 42, Suarez with 61 and Rooney with 70), for Graham for example large parts of the game are closing down defences and making runs to create space for others rather than necessarily receiving the ball. This places much bigger pressure on the chances when they do come and also the lack of shots means it's quite easy to go a few games without scoring through little fault of your own.
Obviously there are numerous other parts to what make up a good striker (which I'll be aiming to look at in later posts). Aside from the likes of van Persie, Rooney and Aguero who can create things for themselves and are far more than just front men, for most teams the main forward is there to take the big chances and Steven Fletcher's stats above combined with 3 goals in 2 games this season show the value in someone who is a proven finisher.
