DJ, Holmes, Hill, Ng, Carter has only been used (from what I can tell) briefly once. -2 result. Only four scoring shots total, a bucket for us and a bucket and two free throws against us.
Assuming AB is Ballinger and not Bruce, your second combo has also been virtually unused but is +2. Only two scoring instances in that time.
Whereas the original starting line-up is: Adam Ballinger,Brad Hill,Craig Winder,Jacob Holmes,Troy De Vries (+11)
(No significance in order of players - just alphabetical by first name to get them grouping properly in the queries.)
The starters after the import changes: Adam Ballinger,Brad Hill,Eddie Shannon,Jacob Holmes,Ron Howard (+24).
Then that line-up, but without Hill is, ranked by combos used (no allowance for time on court, keep in mind):
1. Adam Ballinger,Eddie Shannon,Jacob Holmes,Rhys Carter,Ron Howard (-1)
2. Adam Ballinger,Darren Ng,Eddie Shannon,Jacob Holmes,Ron Howard (-1)
3. Aaron Bruce,Adam Ballinger,Eddie Shannon,Jacob Holmes,Ron Howard (-1)
4. Adam Ballinger,Eddie Shannon,Jacob Holmes,Mitchell Creek,Ron Howard (-23)
I think that -23 is heavily influenced by a horrible run in New Zealand?
The top two five-man combos are completely separate:
1. Adam Ballinger,Brad Hill,Eddie Shannon,Jacob Holmes,Ron Howard (24)
2. Daniel Johnson,Darren Ng,Jeff Dowdell,Mitchell Creek,Rhys Carter (20)
3. Adam Ballinger,Craig Winder,Darren Ng,Jeff Dowdell,Rhys Carter (12)
4. Adam Ballinger,Brad Hill,Craig Winder,Jacob Holmes,Troy De Vries (11)
5. Adam Ballinger,Brad Hill,Darren Ng,Eddie Shannon,Jacob Holmes (9)
6. Aaron Bruce,Daniel Johnson,Jeff Dowdell,Mitchell Creek,Rhys Carter (8)
7. Aaron Bruce,Daniel Johnson,Jacob Holmes,Mitchell Creek,Tom Daly (8)
8. Adam Ballinger,Craig Winder,Daniel Johnson,Jacob Holmes,Rhys Carter (8)
9. Adam Ballinger,Brad Hill,Daniel Johnson,Eddie Shannon,Mitchell Creek (8)
10. Aaron Bruce,Adam Ballinger,Eddie Shannon,Jacob Holmes,Mitchell Creek (7)
