You're only now realizing this? It's been pretty obvious since Mangini got the gig. And it wouldn't have mattered if a different drummer won the "audition". It would have been the same case.
Honestly, no I didn't. I wasn't interacting with the fan base much at the time so I missed most of the Facebook and forum commentaries. I know he has an enormous following but probably underestimated it because he's the drummer! Usually it's the singer or guitarist who can command that amount of loyalty.
And agreed, none of the other drummers would have survived the inevitable sway of the tide because at the end of the day I don't think this has anything to do with job performance. Realistically there was nothing anyone could have done to fend off MP's return.
