Many had criticised Redknapp for not putting faith in young players during his time at White Hart Lane, with the likes of Kyle Walker, Kyle Naughton and Steven Caulker forced to go out on loan before earning their crack at first-team football.
All three players have played well under Villas-Boas, and Walker, who went on loan to Villa the season before last, is now arguably England's first-choice right back.
Villas-Boas thinks Redknapp's loan policy has given those three players the confidence to play well this season.
"I think (Walker) has benefited from going on loan and getting that playing time," the Spurs manager said.
"He has come back stronger, full of ambition. He embraced it, as did Naughton and Caulker.
"We are living at the moment with the benefit from those kind of solutions. It's something we look carefully at."
