They weren't on a hiding to nothing, it was actually a very entertaining series. With or without Evans. I enjoyed it, there were a few episodes which were better than "old" Top Gear. Given I only watched them on iPlayer after a couple of them, I did find myself skipping the Star in a Car bits. They were arguably some of the worst parts of the old show anyway.
Hope the next series is similar to this one actually, in terms of the rest of the presenters staying together - they definitely made it better than the old one for me. You had everything there. Reviews from every angle; the racers, the F1 team principal, the new kid, the car enthusiast and fucking Joey! The pure car enthusiast is gone, but the rest made it anyway.
Good luck to them, think they did more than better than replacing the old crew of presenters.
