Given Lowe's preferred way of playing then the Central CB is the only position Storey is suited to and the fact that he's performed well on loan highlights why we shouldn't offload him unless its for well above £1million and we can sign both our first choice wing-back options with the money.
There's a decent Championship defender in Storey but he seemed to lose his way under McAvoy (but then didn't most of the squad) - his performance at Forest seemed to sum it up when he spent most of the second half saying he'd knock Lyle Taylor out if he wasn't on a football pitch rather than concentrate on his game.
Lowe managed to drag Potts back from oblivion after the Forest game and of all the players who have been out on loan this season; Storey is his best chance of turning another one around.
