Part of the Cubs requirements according to Jim Katt, who at one time applied for a job with them are basically to not criticize to harshly and to promote the "atmosphere" surrounding the team. (i.e. Wrigley Field). Jim told me that in his interview.
Don't know if that's changed since McDonough left (I suspect it hasn't). Jim found those requirements hard to take when he applied and I think he's probably happy he didn't get that job.
