The Ravens are turning their attention toward trying to lock up other pending free agents such as punter Sam Koch and Pro Bowl defensive tackle Haloti Ngata. “We’re going to try to keep as many of our guys as we can,†Ravens director of player personnel Eric DeCosta said Wednesday at the Senior Bowl. The 6-foot-4, 350-pounder is scheduled to be an unrestricted free agent, and keeping him will be an expensive proposition. A contract extension for Ngata could exceed the blockbuster deal inked by Detroit Lions defensive tackle Ndamukong Suh, a five-year, $68 million deal that includes $40 million in guaranteed money. Ngata could eventually wind up making as much as $70 million to $75 million with over $40 million guaranteed. Source: Aaron Wilson, Carroll County Times
