Myself? Some days I'm 60/40 and other days I'm 40/60 that Barr will do the job.
With Sessions of course and his recusal, I was 99.999% sure that he was afraid of the Deep State and that he wouldn't do the job.
I have always felt that while Sessions may not have been complicit, I think he feared someone had something on him and would use it when the hardball started.
I STRONGLY feel that way about Chief Justice Roberts. It is the only way I can explain his swing to the Left...:(
