Dean Saunders will look to add some steel to his Doncaster side next season as they look for an instant return to the npower Championship.
Rovers ended their relegation campaign at the foot of the table with a 3-2 defeat to Ipswich at the Keepmoat Stadium.
"We started the game sloppy, I've never seen us misplace so many passes," he said.
"I thought we played well at Coventry, we got a great result at Middlesbrough, we played well against Portmouth.
"If we'd have won the game - you can't help it, human nature - you go away thinking 'everything's alright, we'll be alright next season'. Seeing that just makes my mind up.
"We've gifted three goals again - it's been happening all season. All the chances they got we gave them."
Ipswich manager Paul Jewell was far from satisfied after his watching his side let their early dominance slip to allow Doncaster back in the game.
"I'm angry today because at 2-0 we were playing well and should have been out of sight," he said. "The chances we've had to go three or four goals up before they scored could have killed them off, but we didn't and then we're always susceptible to concede goals.
"Someone's just said that it summed up the season. For half an hour, until we scored the second goal, we controlled it and looked like we were going to score every time we went forward.
"But then we give teams a foothold in the games because we stop doing the simple things and the unglamorous things that would have got us through certain situations. Once we start thinking we've cracked it we're nowhere near as good a team."
