And the Borders-born Gloucester backs coach wants whoever is at fly-half - currently Greig Laidlaw - to be able share the creative burden with the man outside him.
"The problem position is 12 and I firmly believe that we need a better rugby player there than we have," Redpath, who earned 60 caps for Scotland, told the Scotsman.
"If you want to have a good attack then you need a good inside centre.
"At the moment every move that Scotland do is off ten and, because the pass is made early on, the defence can drift across the field very easily.
"You need the ability to make moves from 12 to keep the opposition guessing so you need to pick a creative force and distributor.
"There are times when a player thinks for a split second about scoring himself and ruins a chance for a team try and Scotland do have some pace out wide if they can find a way to use it."
Sean Lamont is the man in possession of the No. 12 shirt and has been one of Scotland's brightest sparks in attack in the opening rounds.
But Redpath wants to see more variety in head coach Andy Robinson's selections.
"I haven't seen Matt Scott play so I'd stick with Sean Lamont and Max Evans as the centres, although I'd like to see them mix and match, swapping roles occasionally," he added.
