Dublin's problem position
Since Paddy Christie left the stage, Dublin have tried several men in the No 3 shirt, but Rory O'Carroll's consistency has solved at least one of Pat Gilroy's problems which beset his predecessor Paul Caffrey.
Cahill has spent much of his time as a half-back (now he's effectively a midfelder) but in Caffrey's second year his mobility was seen as perfect for the full-back position as time began to catch up with Christie. The second half of the All-Ireland semi-final against Mayo put paid to any long-term future there as the Connacht team produced a comeback that floored Dublin.
He made his championship debut in the daunting company of Graham Geraghty and Joe Sheridan when Dublin played Meath in the Leinster quarter-final. But 30 minutes into the replay he had seen off Sheridan and looked set for a long tenancy on the edge of the square. He had presence and pace. However, two early goals against Tyrone in the 2008 All-Ireland quarter-final set him back.
With McConnell injured, Moran deputised in a 'horses for courses' move. Physical power wasn't essential in the match-ups so Moran fitted the bill on that occasion.
Bastick brought abrasiveness and conviction to the position in Gilroy's first year but Jack O'Connor spotted weaknesses and put Declan O'Sullivan in on him for the All-Ireland quarter-final against Kerry. O'Sullivan's clever play exposed him but Bastick wasn't alone and has since been reinvented with telling effect.
