Perhaps Umaga has some concept about some players being better starters than finishers, maybe he feels others are best suited to tangle with the Crusaders.
No matter what Bryn Hall and Ihaia West say about their move to the bench, at best they must be bemused about that relegation after their solid start to the series.
For too long, the Blues have struggled to find a solid fulcrum and there have been regular glitches in the 8-9-10 combinations at the core of their ambition.
Hall and West have some way to go but last Friday at Eden Park they hinted they were on the right path and getting more in sync with their combination and decisions.
Let's see how they go when they have to travel to Christchurch and guide the side around an unfamiliar ground against stronger rivals like Kieran Read and Andy Ellis close to the set-piece.
Think again. This is a new era and chop and change is the new Blues format.
