Russo has achieved fame and fortune off his schtick because he simply does NOT know his stuff.
Not even his favorite sport of Baseball.
Years ago, he was discussing a play with his then-partner/side-kick Mike Francesa when Russo did not understand one of the most basic rules of the game. He did not know (or believe) that a batter who tries to stretch a double into a triple but gets thrown-out at third base, does indeed get credit for a double. Francesa corrected him, and explained the rule; and Russo was completely unaware.
That is something a kid learns from his father or a little-league-coach. That is something that a forty-year-old-man who claims to be a die-hard, lifetime baseball fan should know ... AND ... if that same man is making a great living discussing baseball, HAS TO KNOW.
I have heard this tape several times on a NYC morning talk show. There are other examples of cluelessness.
In my opinion, there are people out there, that are just not worth listening to.
