Pundits have made a lot of DJR Team Penske's dominance in the early part of the 2017 Supercars championship.
People will rightly point to the addition of former Red Bull Holden Racing Team engineer Ludo Lacroix, who is now working for Penske and alongside Scott McLaughlin. There is more to it than that though.
I think Lacroix would agree his inclusion in the team has given some other directions and he has brought along a lot of information and ideas that I think he might have had bottled up inside. But the team was also making changes before he arrived.
They have some clever people there as well as Lacroix. Phil Key, who is Fabian Coulthard's engineer, is one of the most highly regarded in the lane and has been around for a long time.
The announcement Kiwi McLaughlin was coming to the team also came in line with Penske committing a certain budget to the operation.
