Ryan Miller, G: Miller, 36, signed a two-year contract as an unrestricted free agent July 1 to be John Gibson's backup. The 2010 Vezina Trophy winner and two-time U.S. Olympian is 358-262-73 with one tie, a 2.61 goals-against average, a .915 save percentage and 39 shutouts in 709 NHL games. He was 18-29-6 with a 2.80 GAA and .914 save percentage with the Vancouver Canucks last season. Given Gibson's injury history, Miller is a valuable insurance policy, someone who can give the Ducks quality starts. After years as a No. 1 goaltender, Miller is aware that his role will change in Anaheim, and he is fine with that, noting that the Pittsburgh Penguins won the Stanley Cup last season with a veteran goaltender (Marc-Andre Fleury) helping to supplement the work of a young up-and-comer (Matt Murray). ... Dennis Rasmussen, F: The 27-year-old signed a one-year contract on July 7. He has 17 points and a plus-5 rating in 112 NHL games, all with the Chicago Blackhawks. ... Steve Oleksy, D: The 31-year-old signed a two-year contract on July 2. He adds depth at the position following the departures of Theodore, Clayton Stoner (to Vegas) and Simon Despres (buyout). Oleksy has played 73 games with the Penguins and Washington Capitals since making his NHL debut March 5, 2013. ... Derek Grant , C: The 27-year-old signed a one-year contract on July 2 and has a chance to compete for a role as a bottom-six forward. He has seven assists in 86 games with the Buffalo Sabres, Nashville Predators, Calgary Flames and Ottawa Senators.
