Zbynek Michalek has left the Arizona Coyotes twice. Once by free agency, and once by trade.
Both times, he's returned.
Michalek was dealt to the St. Louis Blues this season at the Trade Deadline in exchange for center prospect Maxim Letunov. With Michalek's return, the Coyotes really gave up nothing to land the prospect.
Zbynek has never blown up the scoresheet; his best year in his second run with the Coyotes was a two goal, eight assist campaign in 2012-13, but Michalek is still important for other reasons.
His totals likely benefit from partnering with Oliver Ekman-Larsson for much of last season, but Michalek is still a highly capable shot-blocker and penalty killer.
