Former Arizona Cardinals coach Ken Whisenhunt will become the offensive coordinator for the San Diego Chargers, a league source told Adam Schefter of ESPN. The Chargers hired former Broncos offensive coordinator Mike McCoy as their new coach this week. Whisenhunt was dismissed by Arizona on Dec. 31 after six seasons. He led the Cardinals to their only Super Bowl appearance in his second season and Arizona won its second straight NFC West title the following year. But after a 4-0 start this season, the Cardinals lost 11 of their last 12 to finish 5-11 for the second time in three years. Source: The Redzone
