The Giants' search for an offensive coordinator has expanded. Green Bay Packers quarterbacks coach Ben McAdoo will interview for the job this weekend, according to a person familiar with the situation. McAdoo joins former Giants assistant Mike Sullivan and ex-Titans offensive coordinator Dowell Loggains. Sullivan and Loggains met with the Giants on Wednesday as the team looks for a replacement for Kevin Gilbride, who retired last week. Prior to their interviews with the Giants on Wednesday, no other candidates had interviews scheduled with the team. But Wednesday night the Giants arranged a meeting with McAdoo, who has also interviewed for the Browns head coaching job this week. McAdoo, 36, spent six seasons as the Packers’ tight ends coach before the past two years as Aaron Rodgers’ QB coach after Joe Philbin left to become head coach of the Dolphins. Rodgers said on his weekly radio show that the up-and-coming coach should use him as a reference.
