They had some falling out?
According to interviews, JimTom likes to run his mouth too much.
And the golden rule for anyone doing any type of questionable activity is KEEP YOU MOUTH SHUT.
They did have a falling out, but I don’t think exactly what happened is clear. It was brought up on the roundtable episode they had a few weeks back. Mark and Jeff just said they weren’t happy with Jim Tom and they probably wouldn’t be working with him again.
