The New York Giants never really opened their search for a general manager when they hired Dave Gettleman. Sure, they interviewed Louis Riddick. He was, though, the only candidate from outside the organization to receive an interview.
The way the Giants did that apparently did not sit well with some around the NFL, per Tony Pauline of Draft Analyst:
Multiple sources tell me there were a lot of feathers ruffled when the New York Giants hired Dave Gettleman as their general manager.
Sources feel Gettleman was the favorite of former Giants general manager Ernie Accorsi and was hired based on his previous tenure and familiarity with the organization rather than the franchise doing an exhaustive search for the best person for the job.
