Russo on his longevity in the dog-eat-dog world (no pun intended) of sports radio, on what got him fired up about sports talk when he was a kid, on how he lasted 19 years with the bombastic Mike Francesa, on his secret to good radio, and on how in the world he can have so many strong opinions about so many things in the world of sports.
