A goal down with twenty minutes remaining, a touchline conference between Colin and former reserve coach Chris Hughton resulted in Simon Davies moving to a central position, Leo switching to the right and Yannick Kamanan heading left.
This allowed Sergei Rebrov to push up after playing in a withdrawn role behind the strikers and Bingo - a 1-0 deficit was transformed into a 2-1 victory.
Colin, however, deflect praise of the switch onto the first team coach.
"Credit to Chrissie Hughton," said Colin. "He came down and said do you fancy making a switch. The way it was set out, we weren't in control of the game really.
"We pushed Sergei up a bit and, whatever happened, we scored pretty soon after that and it gave us a lift. Then we scored off a set piece three minutes later.
"When you look back at it, it was a very good reserve game. Two teams that were probably nearly equal in quality and experience and I would imagine it was fairly enjoyable for the people watching.
"We made mistakes, they made mistakes, but overall they played the way their first team play and we played in a way that Tottenham would want to play.
"I'm delighted we won in the end, but it definitely flatters us that we ended up winning. I thought our performance was fairly good and a lot of things were done right, and we deserved to get something.
"I was delighted when we scored and if had ended up a draw I would have thought that was probably fair."
A spot of tactical tweaking was credited by Colin Calderwood for sparking Monday night's reserve win over Fulham at Stevenage.
