But the All Black scrum half is sidelined for the next seven weeks with a foot injury, and to make matters worse, it has been confirmed muscular Mike Phillips will miss the start of the Heienken cup with on going knee troubles.
However, Holley says that his two young guns, Rhys Webb and Rhodri Wells have the abilities needed to dictate a game from behind the scrum.
He told the South Wales Evening Post: "The two youngsters are doing okay and don't look out of place in regional rugby.
''That augurs well and sometimes when young players are given a chance to have game time they show what they can do.''
That said, Holley belives it might be necessary to bring in additional cover for the forthcoming weeks. ''We will see whether we should try to bring in someone else. We will assess how long Mike is going to be out, but going into a phase of the campaign when we play EDF Energy, European and Magners League matches, we need three scrum-halves."
Holley also has the option of switching Shane Williams to the pivot position. Williams is a former nine but would be missed on the wing where his talents are best employed
ERC player registration passed last weekend, however, teams may nominate an additional player to their squads in each round of the Pool Stage, providing they also de-register a player to retain a maximum squad size of 38.
