Corby Town suffered another defensive horror show as they were beaten 5-4 at home by Bradford Park Avenue.
The Steelmen, who slipped to their fifth successive loss in the Blue Square Bet North, shipped four first-half goals as they again made costly errors at the back.
They did produce a spirited late fightback with two goals from Josh Moreman but it was to no avail.
Sampson rang the changes after four successive defeats with Jason Crowe moving to right-back while Tom McGowan, Sam Ives and Moreman were all handed starting places.
The Steelmen also named new signings Tom Ingram and Marc Magna, who boasts Bordeaux and Rochdale as two of his former clubs, on the bench.
Corby started brightly enough but the visitors were soon into their stride and there was a big let-off after 10 minutes when Jordan Deacey got clear and smashed his shot off the corner of post and bar.
Sam Ives shot wide for the hosts but, almost immediately, home goalkeeper Paul Walker was forced into a fine save by Danny Holland.
And when the opening goal arrived, it was extremely unfortunate.
Richard Marshall’s fierce free-kick cannoned back off the crossbar but it hit Walker and dropped into the net.
From there, it was nothing short of a disaster for the Steelmen.
Substitute Tom Greaves made it 2-0 when he converted Danny Holland’s cross and an awful mix-up between Pierrick Briand and Walker allowed Greaves to roll the ball into an empty net for number three.
McGowan and Leon McKenzie did test visiting goalkeeper Tim Deasy before McKenzie pulled one back from close range after Paul Malone’s header had been cleared off the line.
But it was 4-1 before half-time as Holland fired past Walker after more weak defending from Corby allowed him too much space.
The goals continued to come after the break as well.
Holland made it 5-1 as he was left unmarked to score from Greaves’ cross and almost immediately, McKenzie pulled another back as the ball rebounded off him as Deasy tried to gather a loose ball.
Holland should have made it six but headed wide and, from there, the game became scrappy with Bradford happy to sit on their lead.
There was little goalmouth action until the final few minutes when a post denied Holland his hat-trick.
Corby did manage to cause a few nervous moments towards the end however as Josh Moreman pulled one back with a glancing header before firing home in the third minute of stoppage-time to make it 5-4.
But an incredible comeback wasn’t quite possible as that dreadful first-half display proved so costly.
