I think Balogun is competition for Sporar and Connolly is competition for Watmore. Balogun seems to have similar skills to Sporar while Connolly and Watmore seem quite similar. Unless Hernandez is going to be reinvented as a left wing-back or left-sided attacking midfielder I can see him going back to Norwich.
As far as I can tell, Wilder is trying to get two players in competition for each outfield place or to at least have a decent back-up for each place.
Dijksteel - Peltier
Fry - Bamba
McNair - ?
Jones - ?
Crooks - Payero
Howson - ?
Tav - Lea Siliki/Boyd Munce
Bola - Taylor
Watmore - Connolly
Sporar - Balogun
That does leave Uche, Coburn, and Hernandez quite a way down the pecking order though with Bola out for a long period we're struggling for cover at left wing-back.
