I think he might be referring to either James Jones or Roscoe? (possibly the former?)
Yeah, to put it another way: we don't need another [insert position here] - yes that's true as things stand, but might not be the case in a week's time, we don't know.
And if we choose to release (or someone doesn't sign a deal) we should now be looking for a replacement that we feel confident will be starter quality... for promotion / League Two, not starter quality for what we were this time last year (or the year before).
Not just referring to the centre back situation here - the same is true of finding a midfielder that could threaten to bench Elliott or Isaac, or a winger that could bench Justin or Alex.
The 'starter quality' goalpost moves.
