I've just used the excellent Everton Results.com and the likes of wikipedia (hence why some figures may be ever so slightly out) to list how many strikers we've had under Moyes and their conversion rate.
Now bear in mind that this list focuses solely on #9's and doesn't include the likes of Steve Watson, Fellaini, Cahill, Donovan, McFadden, Naismith or Kevin Mirallas, who have spent the majority of their Everton career playing elsewhere.
Duncan Ferguson: 20 goals in 102 appearances, a conversion rate of 1 in 5.
Tommy Radzinski: 20 goals in around about 55 appearances, a conversion rate of 1 in 2.75.
Nick Chadwick: 6 goals in 17 appearances, a conversion rate of 1 in 2.8.
Kevin Campbell: 13 in around about 70 appearances, a conversion rate of 1 in 5.3.
Wayne Rooney: 17 goals in 177 appearances, a conversion rate of 1 in 4.5.
Brian McBride: 4 goals in 8 appearances, a conversion rate of 1 in 2.
Francis Jeffers: 2 goals in 22 appearances, a conversion rate of 1 in 11.
Marcus Bent: 8 goals in 66 appearances, a conversion rate of 1 in 8.25.
James Beattie: 15 goals in 86 appearances, a conversion rate of 1 in 5.7.
James Vaughan: 9 goals in 60 appearances, a conversion rate of 1 in 6.5.
Andy Johnson: 22 goals in 74 appearances, a conversaion rate of 1 in 3.3.
Victor Anichebe: 24 goals in 154 appearances, a conversion rate of 1 in 6.5.
Yakubu: 33 goals in 107 appearances, a conversion rate of 1 in 3.2. *
*His first season with us and his sole season with Blackburn yielded a conversion rate of 1 in 1.8, which clearly shows how horribly mismanaged he was since f*cking Blackburn managed to serve him up with a glut of goals.
Louis Saha: 35 goals in 115, appearances, a conversion rate of 1 in 3.2.
Jo: 7 goals in 35 appearances, a conversion rate of 1 in 5.
Jermaine Beckford: 10 goals in 40 appearances, a conversion rate of 1 in 4.
Apostolis Vellios: 3 goals in 24 appearances, a conversion rate of 1 in 8.
Denis Straqualursi: 3 goals in 27 appearances, a conversion rate of 1 in 9.
Nikica Jelavic: 18 goals in 44 appearances, a conversion rate of 1 in 2.4.
Now, of course pure stats don't tell the whole story, because if they did we seemingly dropped an almighty b*llock in letting Brian McBride go...but this list does go some way in telling us where our problems lie.
For a famously settled and close knit first XI in which the likes of Osman, Hibbert, Neville, Howard, Cahill, Arteta, Baines and Jagielka have/had played together for well over 5 years the sheer amount of centre forwards that we've gone through is quite startling, especially considering that we've played with 1 up top for the best part of 8 years.
Including the lads that have had to do a job up front or do play centre forward elsewhere (i.e. Cahill, Naismith, Fellaini, McFadden, Donovan) I count a total of 26 strikers that have been utilised under Moyes in his 11 year tenure, that's over two per season.
As mentioned before, take a starting XI from 2007 and in Howard, Neville, Hibbert, Jagielka, Baines, Osman and Pienaar there's 7 players out of a possible 11 that make our first choice XI to this day, Moyes clearly likes his favourites and of course they've served us brilliantly but the further we get up the pitch the clearer it gets that our play will never suit an out-an-out striker.
It's not like we've had our precious striking talents snatched away from us by those in the upper echelons of World Football either, out of that above list only Wayne Rooney has gone on to bigger and better things...that's one centre forward out of a possible 26 that's been deemed good enough for a stronger club than ours to bid for.
The combination of poor buying (Beattie, Johnson and Yakubu were all club record signings), a lot of dross and a frankly undeniable aversion to playing simply to a strikers strengths continues to cost us, the latest victim in Nikica Jelavic still has a very respectable conversion rate of around 1 in 2 but as has been said in this thread, he's clearly being asked to do a lot more whilst recieving less in return, time shall only tell how he will continue at Everton but I for one am not expecting too much.
