London coach Joe Grima admitted it was a "tough day" for everyone connected with the Broncos after their 72-12 hammering by Warrington Wolves confirmed their relegation from Super League.
Following Salford's victory over Hull on Saturday, this crushing loss saw the Broncos drop out of the top flight for 2015.
The rampant Wolves made it 10 wins in succession as they had far too much power and pace for Super League's basement dwellers, running in 13 tries.
Winger Joel Monaghan claimed four tries with second row forward Ben Currie and prop Chris Hill both scoring hat-tricks, with the other tries coming from Ben Harrison, Paul Wood and Gene Ormsby while Chris Bridge landed 10 goals.
London's points came from tries by Joe Keyes and Scott Moore, with Josh Drinkwater kicking both conversions.
An emotional Grima admitted it was a difficult day for his side, and he said: "I'd swap my position right now for anyone. It's a privilege to be coaching at this level but it doesn't get tougher than this. It's a tough day for our club.
"Since I took over we have had a plan A and a plan B. We knew where we were and there were no false illusions by myself or the staff and have been planning for relegation and the Championship.
"We have already made some good Australian-based signings which we will announce soon and 23 players will be moving on.
"It's been a tough 12 months with being on the brink of administration, losing players out of our squad only six players doing an off season and we recruited a squad of 31 players.
"We will be starting again from scratch in the Championship and because we have been realistic it will be a benefit to us."
Regarding the 72-12 defeat Grima admitted it was the first time as a coach he had been on the wrong side of such a result.
He added: "As a coach I have never been beat by 72 but you get experience in adversity as well.
"However Warrington seem to do it to us. They put 80 on us last year at home and two years ago put 80 on us at our place so at least they didn't get the 80 this time I guess.
"We've now got to get the foundations right for next year and - to be honest - the players are not proud of how they have been playing.
"It doesn't demonstrate how they have been training but today looked like men against boys and maybe that's where we are really at."
Warrington coach Tony Smith had little sympathy with London's plight after watching his side run in 13 tries against the Broncos.
Smith said: "For the London club and for Super League it's a lesson to be learned. It shows you how not to get ready for a rugby league season.
"London are paying the price for having a handful of players at the start of the season while the rest of us when were honing our skills and doing the hard work in November and December for a long and arduous contest.
"When you start the season with just a few players do you expect anything else? It didn't matter who was the coach it was a year for relegation and being so under prepared of course they were going to get their backsides kicked.
"And if they didn't you would have to look at the rest of us in the competition because of the advantage that we had.
"It's how not to do things and how not to improve the standards of Super League by letting clubs in when they were so ill-prepared like London were."
Regarding his side's performance, Smith was delighted by the display of four-try hero Monaghan, and he added: "I thought Joel had some fantastic touches and finished off some great plays but I thought he set the example by not over doing things.
"It could have hampered us today if we had played with a lack of control but there was good team discipline.
"It was a strong and well-disciplined performance which could easily have got out of hand by throwing the ball around willy nilly and trying to score off every play."
