Just to update a stat from a few weeks ago.
Goals conceded per 90 mins when playing at centre back this season:
Canavan 1.42
Watts 1.69
Aimson 1.72
Wootton 1.72
Opoku 1.82
Criminally, criminally underrated centre back. No further comment.
I probably agree that Canavan is (was) one of our best three defenders, but your stats don't control for multiple variable factors.
For example, 7 of the 10 league games Opoku has started came against teams currently in the top half of the table. For Canavan, the figure is 4 out of 10.
Opoku has started 4 league home games and 6 away, Canavan 7 home and 3 away.
When you attempt to control for difficulty of games in order to make the comparison fairer, we actually concede fewer with Opoku in the side.
In league away games, it's 1.9 goals conceded per 90 minutes with Opoku vs 2.1 with Canavan and for games against current top half teams it's 1.7 Opoku vs 2.2 Canavan.
(I don't think my stats prove a great deal either - other than that football isn't a precise science and it's usually worth looking under the bonnet of any statistic.)
