Either way, Budaj got a rest, the Avalanche pressured the Flyers (0-3-1) early and relied on Raycroft's steady play in goal and captain Joe Sakic's three assists to pull out their first win of the season.
The goals Raycroft allowed came on a 5-on-3 power play and a penalty shot.
Budaj has allowed 13 goals in three games, all one-goal losses. Raycroft signed this offseason with Colorado after Jose Theodore bolted for Washington as a free agent. Raycroft started 16 games for the Maple Leafs last season, going 2-9-5.
Raycroft's teammates made sure he wouldn't have a pressure-filled debut for the Avs.
The Avalanche outshot the Flyers 17-3 in the first period and got goals from Brett Clark and Marek Svatos, who scored on a power play, to take a 2-0 lead.
Sakic sent a cross-ice pass to Clark, who one-timed it through Martin Biron's legs for his first goal of the season. Then, Ruslan Salei sent the puck across the ice to Wojtek Wolski, who sent it down into the slot and Svatos put the puck over Biron's left shoulder.
The Flyers scored twice in the second period but both times the Avalanche quickly responded with goals of their own and took a 4-2 lead into the final period.
Milan Hejduk needed less than a minute to reply to Simon Gagne's goal on a penalty shot, and Cody McCormick responded to Mike Richards' one-timer on a 5-on-3 advantage with a goal that scooted past Biron with just 35 seconds left in the second period.
With seven minutes remaining in the game, Paul Stastny scored on a 5-on-3 power play to make it 5-2.
