Completely serious. Did you ever see him live with Chiodos? It was mind numbingly boring compared to Craig's performances. Agreed that Craig's vocals aren't always spot on.
So yes Jack, I'm being serious. There is a reason his stint with the band was short lived.
I saw him live 4 times with Chiodos, and he killed it every time. I was highly impressed with him, on both his own songs and Craig songs.
And the reason he was out of Chiodos so fast was lack of success, combined with internal fighting. Chiodos fans made it clear they're more interested in personality than talent. I'll give you that his stage presence wasn't great, but I'll take an amazing vocalist with no presence over a horrible vocalist with great stage presence.
