Wolves manager Kenny Jackett believes last summer's exodus from Molineux actually helped the club in their Sky Bet League One promotion fight.
Wolves secured promotion back to the Championship with victory over Crewe on Saturday and Jackett, who allowed the likes of Karl Henry and Christophe Berra to leave the club last summer, believes an overhaul was needed after back-to-back relegations.
The former Millwall boss told Sky Sports News Radio's FL72 Weekly show: "Moving on a lot of the big earners has helped us to regenerate from the bottom.
"That's what the club needed after some relegations and also what a lot of the players needed; they needed a fresh start to move on personally to their next challenge.
"And for the crowd to focus on a new group, that's the most important thing, and what we have here now is a new group that want to make their mark at Wolverhampton."
Wolves are six points clear at the League One summit with four games remaining and Jackett admits it would be a disappointment were they not to win the title from this position.
After that, Jackett confirmed plans for the summer transfer window are already well underway, but he has faith in his current squad to make the step up.
He added: "You never sit still, and we want to win the league. For most of us it would leave a bitter taste if we didn't do that.
"We will need to strengthen but you always need to improve, you always need to freshen up.
"I wouldn't say, though, that we need major surgery, I'm very confident that the 20 or so players that we have here can go into the next division and do well.
"Naturally we'll be looking to improve, but without ripping things apart like we needed to do last summer.
"It's a fantastic division the Championship. Before this year I'd spent the last three years there and know it very well. It's a tough league to get out of but like most of the division we'll start on the line with aspirations of getting to the Premier League."
Sky Sports pundit Garry Birtles was full of praise for the job Jackett has done at Molineux and agrees with the 52-year-old that the Black Country outfit already have plenty of players capable of playing in the Championship.
He said: "It's a magnificent job (that Jackett has done) because Wolverhampton Wanderers in that division are strong favourites because of their history and where they've come from in a very short space of time.
"That brings it's own pressure. It's not easy because every team that goes to Molineux treats it as a cup final. The consistency they've shown over the season has been superb.
"I think they have got players that can compete in the Championship and I'm sure Kenny will be given money over the summer to reinforce that squad.
"You've seen teams come up and make a fantastic fist of it in the Championship so there's no reason why Wolves can't with their experience.
"They have also got some goalscorers - if you have goalscorers at any level, you've got a chance.
