Mr. Stroll has proven that you can buy intellectual property from other teams and put it to work with instant success. Without Dan Fallows, they are probably a very average mid pack team right now. This has implications for the sport. What Ferrari , Mercedes and McLaren would do to know those secrets now.
What did Mr. Stroll pay to get Dan Fallows? Lets say he's making 3-4 million dollars a year and it goes against the cost cap. Sure. He has probably settled into his new role at Aston Martin. But what if Ferrari or McLaren offered him 10 or 20 million ? And they could structure it like a signing bonus and not count it under the cost cap or something. It would be worth it for them. McLaren is sitting at rock bottom with millions worth of problems to sort out. They have sponsors that want to see results. As does Ferrari. It would be worth it for them to just head hunt with big checks.
Even under the cost cap, they could halt all development and just save all the money to sign Fallows. Pay him 20-30 million of the cap in one year. Then give him a normal salary the year after. What are the rules in this regard ?
Adrien Newey was offered movie star money (his words) from Ferrari. But this was before these new regs and the cost cap. The previous era of Mercedes domination was thought to be more about the engines than the aero. Now there is a few major teams on the back foot with tricky new regulations. And just a handful of engineers that know how to make it work.
