He was still "confused" after his deadline attempts to make them even better didn't pan out.
Anaheim swung no major deals Wednesday despite getting deep into talks on a handful of available players, Murray said before his NHL-leading Ducks faced the Montreal Canadiens.
The Ducks made three moves a day earlier, acquiring defenceman Stephane Robidas from Dallas and shipping out forward Dustin Penner and goalie Viktor Fasth. The moves bolstered Anaheim's defence and provided clarity at two crowded roster spots.
But the Ducks didn't add another top centre to boost their depth and faceoff effectiveness, and Murray wasn't sure why he failed.
Anaheim was known to be interested in Vancouver's Ryan Kesler.
