Ben Harding has scored only two goals this season but both have produced crucial 1-0 victories, the midfielder grabbing the winner on Saturday as Cobblers edged past Oxford to maintain their promotion push.
Boothroyd said: "Every time we have the bad weather we have lots of people turn up to help us out and when you have commitment like that it's only right that you repay those people.
"To get the three points is terrific although I thought we did our best to give them at least a point in the second half. When you're in front you have to make sure you play the game in their half but there were three or four occasions when we just gave the ball back to them.
"It's a difficult one for me because I wanted to go in there after the game and shout at them but we won so I didn't, I just left them alone. I'll tell them off on Monday. Our goalkeeper was terrific for us and the first-half performance was very good. It's a very good result for us."
