I don't think they'll have to perform miracles, apparently Danny Ric was starting to get close to Checo and Max laptimes in the sim, performed well on the tire test and they know the Alpha Tauri is a dog. This move is just to get a good measure of him vs Yuki, I think.

It will be mostly down to whether Checo gets his shit together or not. Solid points doesn't really matter, WCC and WDC are both a lock this season off of Max alone. What RB needs is confidence that the second driver can consistently support Verstappen at the front next season and beyond, on the off chance that other teams catch up.
