When the Las Vegas Raiders hired Pete Carroll this offseason, they did so because, well, for one, they missed out on their top candidate, Ben Johnson. But they ended up settling on Carroll because they felt good about his wealth of experience, winning pedigree and ability to build a culture.
But nobody has ever accused Carroll of being able to put together a good staff. He hit the jackpot in the early 2010s with Dan Quinn as his defensive coordinator and Robert Saleh as his defensive quality control coach. When those two left, so did any real playoff success in Seattle.
