From the Associated Press:

BRISTOL, Conn. - This season's “College GameDay” on ESPN will feature entertainer Nick Lachey providing features as a regular contributor, including onsite appearances.

“Nick is a huge sports fan and will add a unique perspective to the show,” said Norby Williamson, senior vice president and managing editor for ESPN. “He will provide wide-ranging, off-the-field features spotlighting the tradition of the game, its fans, athletes and personalities.”

As you'll recall, the Cincinnati Enquirer published a guest commentary by Mr. Lachey at the end of May blasting the management for DFA-ing Graves. So at the very least, we know he has plenty to say about sports.

If he catches on, maybe he'll pull some strings and get the Reds some better ESPN coverage.
