This post makes absolutely no sense whatsoever. I don't understand how you, or anyone else for that matter, can imply that the drummer wasn't the problem.
I'll give you an example...
The rhythm guitar player is constantly too loud and dialing in way too much low end... It's the drummers fault. The drummer is obviously too loud and tuning his drums wrong forcing the poor guitar player to crank and chug...
Here's another...
The lead vocalist can't make it to gigs in time to help set up the PA or do a soundcheck... It's the drummer again. The drummer obviously has too many drums that always take forever to set up. The singer just sat around waiting to lift speakers onto poles and run cables. Then, when the drummer was all set, it took the whole soundcheck for him to get the 5 snare drum mics perfectly aligned so there were no phase issues and that signature ping could really pop in the mix. By the time he was done the singer had lost his voice doing warm ups for way too long. Now he sits in the car drinking tea and doing breathing exercises so he's ready to go as soon as the lights go down.
Fire the drummer and welcome the singer back into the band comradery.
See...
