Mike Fisher, Acquired from Senators for a 1st Rd & 3rd Rd Pick in 2011
This wasn't an easy choice for the Senators to make at the time. Mike Fisher has talked about how "life changing" this trade to Nashville was for him and his family, including his wife Carrier Underwood.
Fisher came to the Predators that season at age 30 and quickly became a stabilizing force of leadership for the locker room. He brought winning pedigree as the Predators gradually became a more legitimate postseason team.
Up to this point in Predators history, the franchise was nothing more than a 1st round punching bag at best. Fisher helped cultivate a new winning culture as other franchise greats came into their own.
Fisher went on to play in 71 playoff games for the Predators, and put up 24 points which is tied with three other players for 10th in franchise history.
The Senators got a couple draft picks out of the deal, but never saw either player used with those draft picks appear in an NHL game for them. So yeah, this is easily one of the most significant trade deadline deals in Predators history.
