Voss admitted after the Lions' 10-point win against the Bombers at Etihad Stadium that his team had lost its "mojo" since winning this year's NAB Cup, with the Lions' only wins in the first seven rounds coming against Gold Coast and Melbourne.
Voss said he had no idea how the Lions had fallen away from the fast-moving brand of football they played in the pre-season competition, but said belief and persistence had been the keys to their turnaround against Essendon.

"Probably the most asked question has been what's happened since NAB Cup," Voss said.
"We did lose our mojo and we've been steadily getting that back and to get that back you've got to have a playing group that believes in what you're doing.
"They've been terrifically proactive in the way that they've gone about trying to remedy the situation and the accountability they've put on themselves to make sure they turn it around.
"But it's a big pat on the back for the playing group because they've really taking some genuine ownership and accountability about how we're going and everything I've seen behind the scenes is about … trying to make sure that we turn it around and we turn it around quickly."

Asked whether he had questioned himself as coach after a start to the season that had included three 10-goal losses, Voss said he had simply focused on doing his job.
"My focus has not changed off that, the board's focus has not changed off that and we'll continue to do it until I'm told otherwise," Voss said.
"But I believe in our guys and I believe in our players.
"We've got a good group coming through and they're capable of moments like [today] and I'm glad that with all the work that they've done they've got a little reward."
Sitting alongside Voss at his post-match press conference was forward Dayne Zorko, who was won one of the Lions' best against the Bombers with 19 possessions and three goals, including the one at the 20-minute mark of the final term that put the Lions in front for good.
Zorko said suggestions the Lions players had not been playing for their coach in 2013 were way off the mark.
"Vossy's game-plan is Vossy's game-plan and we back it in 100 per cent and we try and execute it every week and I guess for the first few rounds it just wasn't there," Zorko said.
"But over the last four weeks we've felt like it's started to come back together and we just haven't played the whole four quarters out.
"Today we've finally [played] four quarters and we can see what we can do. We can move the ball all right, we can pressure up and really attack."
Voss said the Lions had focused on being aggressive against the Bombers at the start of Saturday's match to help overcome their recent poor starts.
Voss acknowledged that approach might result in his team crossing the line occasionally, like Daniel Merrett and Justin Clarke seemed to do in first-term incidents with Michael Hurley and Elliott Kavanagh that are likely to be scrutinised by the Match Review Panel.
Merrett slung Hurley to the ground in a tackle that left the Bomber spearhead concussed, while Clarke crashed into Kavanagh's back late in a marking contest.
"You're going to walk a line sometimes and we've got to walk that line a little bit more," Voss said.
