Maturecasfan No idea... all good points, however if you consider this season we've had players dropping like flies.
We started this season with options in most positions, however due to injuries (which seem to have hit the majority of teams in SL, and not just us) we've ended up with a massively patched-up squad with several players playing out of position.
If we end up with another season like this one, then we probably will need the strength in depth in the halves. I think the main issue will be, as you say, keeping them all happy with appropriate game time.
