Shaun Miller scored twice on his full league debut for the Blades with Neill Collins and Chris Porter also finding the net. Boro skipper Mark Roberts struck at the end of the first half to make it 1-1 at the break.
"From start to finish we did enough in the game to suggest we deserved a scoreline like that. We dominated from the first minute but unfortunately we were undone by a set-play just before half-time," said Wilson. "We told the players at half-time to just keep doing what they'd been doing. We were creative and put some dangerous balls into the box which they had difficulties dealing with.
"In the second half, we took our chances very well. Shaun Miller did very well and he's being doing well all season, in fairness, but he's been unlucky.
"We had a look at Shaun out wide a couple of games ago and that position is not really suitable for him so we put him in the middle and tried Nick (Blackman) on the wing. I thought Nick did very well at times.
"It's great to score four goals at home because the fans have witnessed some good football this year without the end product. They got the end product this time and there was a bit of swagger about our play at times, which is great."
