The Seahawks lost a key front office member to resignation on Wednesday. Scot McCloughan, the team's senior personnel executive, unexpectedly resigned to tend to a family matter, league sources told CBS Sports NFL Insider Jason La Canfora.

McCloughan had been with the Seahawks since being hired in June 2010. At the time, Seahawks general manager John Schneider said the team was hiring McCloughan because he was a 'proven talent evaluator.'

Schneider's not kidding either. During five seasons in San Francisco (2005-09), including two as the 49ers general manager, McCloughan was responsible for draft classes that included Frank Gore, Vernon Davis, Patrick Willis and Michael Crabtree.

In Seattle, McCloughan was Schneider's top aide who helped the Seahawks general manager find key draft talent like quarterback Russell Wilson and cornerback Richard Sherman. McCloughan and Schneider interviewed Wilson at the Senior Bowl for over two hours in 2012.
