In today's era of the CAP, if Ngata doesn't want to restructure, then it seems wise to let him go. The Ravens can take this chance because their existing depth is damn good....but they have to augment that depth. There will be a drop off but it shouldn't be too bad. It's like when the Ravens lost Goose and Adams. Who filled in? Buddy Lee. At first I thought "We're screwed", but he was fantastic.
