Exactly! That 23 includes Spence and Walker who haven't remotely come close to playing a full senior season. Plus Pears and Coulson who in my eyes are still not senior pro.
It obviously doesn't include Browne or Bola, but does have Nmecha and Roberts. Plus it hasn't included players like Liddle, Wood, Reading and O'Neill.
So all in all you are probably looking at 17/18 senior pros. 4 of which have been injured for all 9 games in the last 32 days. Plus then Ayala being injured for the last 5 games we have played.
