The three don't skate together nearly as much as they used to, and Ducks coach Bruce Boudreau is quick to say that their reunion is a short one.
But Bobby Ryan has been put back on the top line with Ryan Getzlaf, and Corey Perry and the power trio displayed what happens when they are all clicking in the Ducks' 4-2 triumph over the St. Louis Blues on Sunday night at Honda Center.

Ryan provided the tying goal early in the third period and Perry got the winner a short time later before adding an empty-net score to wrap up another victory for the Ducks, who haven't lost more than one game in regulation at any time this season.
Getzlaf and Perry have been together for seven-plus seasons while Ryan has often played on other lines during his five to spread out the scoring, particularly since Bruce Boudreau became coach early last season.
Ryan has been filling in while Kyle Palmieri has been out for four games because of an upper-body injury and he's recapturing some old memories of the three dominating as a unit.
"It's been good," Ryan said. "The line being back together is more of a product of an injury than anything else. I think we're all aware of that. It's comforting to know that you can go back in and I've played with them so long and I know where they like to be.
"And we've clicked right away."
The three started slowly as they've often done throughout their careers, but they've taken the reins of the Ducks' potent attack of late.
