That was not the point of BigA's reply. Surely SXM knows who he is - a large majority of the *listening public* outside of the NYC Metro is not aware of him.
Case in point: when ESPN ran a 60 minute version of their "30 for 30" documentary series on "Mike and The Mad Dog" a few years back, it was one of the lowest rated shows of that series.
Even though Christopher Russo has more of a current national platform with his SXM and MLB Network TV shows, those are still very niched programs.
Francesa's forays into expanding the reach of his Sunday morning program either for his "NFL Now"/"Football Sunday" program via CBS Radio's sports-formatted stations or the "Sports Now" program that aired from February-September 1995 via Westwood One (I think) flamed out after relatively short periods.
Yes, Mike was a college football + basketball analyst for CBS TV network - but that was in the late 1980s-early 1990s.
