I'm not specifically suggesting we sign Cranie, or Stearman. They just felt like good examples given the role they performed for us in the Championship.
But solid Championship performers like Jack Robinson - for me, are much better cover than Jagielka & Rodwell, on the basis that they have recent experience of playing consecutive 90 minute games at a decent level... sure, there'd be a drop off in quality (which we saw with J Robinson), but in a back 5 like ours you can probably afford to carry one player slightly below par quality wise.
Much harder to carry a player that isn't fit enough. Impossible to carry someone that simply can't get on pitch.
