The team confirmed the three-year deals with Ericsson and Eaves on Friday. Miller told The Associated Press he reached a two-year agreement just before a noon deadline when he would have become a free agent.
Ericsson has played four seasons in the NHL, all with Detroit. He set career highs in 2010-11 in games (74), points (15) and penalty minutes (87).
The 27-year-old Eaves is coming off a season in which he had 13 goals and seven assists in 63 games for the Red Wings.
