Is Jimmy Garoppolo a Good QB?

I wouldn't be shocked if Darren Waller is maybe, you know, a potential trade candidate for other teams. I am fascinated to see what would happen with the Raiders if all those guys were healthy. Mack Collins even stepped up last year as a second option opposite Devonta Adams. So what about the Garoppolo move for the Raiders? Does that keep them out of the QB market at seven? Is this Jimmy the Bridge here? Or do they think they can win with him?
