We discuss the Ravens decision to cut ties with defensive coordinator Don "Wink" Martindale. His unit finished last in the league in passing defense but was decimated by injuries all year. Was the move justified? Who is next in line for the job? And in light of the Chiefs-Bills instant classic, should the NFL again revisit its overtime rules? We take a closer look at John Harbaugh's "spot and choose" concept, and Daniel Wilcox has an idea of how to fix overtime with an interesting approach based on the college overtime model.
