After all, Reilly has had to put up with his nightmare of a boss, Jeff Zucker, and those repeated rumors all last year that Reilly was getting canned. And that nastiness was emanating mostly from Zucker’s office because, as one high-placed TV agent told me at the start of the season, “Jeff’s been a total dick to him. All you can ask of a network entertainment president is a hit a year. Kevin got full credit for My Name Is Earl and fell on his sword to keep The Office. This year, he has Heroes.”
