Dundee United have only lost one out of five games, against Celtic, since McNamara moved from Partick Thistle to Tannadice less than two years into his managerial career.
McNamara displays the same quiet authority as a manager that saw him captain Celtic and become a Scotland regular.
But Butcher insists that cannot last in the Clydesdale Bank Premier League as he prepares to welcome United to the Tulloch Caledonian Stadium.
Butcher said: "Jackie is great. He was an excellent player and has obviously done very well at Partick Thistle as a manager.
"He has a good team around him and also a good team on the pitch as well.
"He has come in and put down his philosophy but he hasn't changed a lot, because there is no need to really change much because they have a good side there and a side that is more than capable of winning matches and climbing the league.
"When you look at Jackie on the sidelines, he just stands there with his arms folded and doesn't really say a lot.
"I'm sure that will change, I'm sure he will be ranting and raving and screaming and doing everything that we normally do, the rest of the managers.
"I'm sure he will get into that habit but he looks cool, calm and collected and he is in charge of some excellent players."
