Coming this fall to a basketball arena near you: Mad Dog and the Mayor.

Continuing their blistering offseason pace, the Timberwolves added two role players to their roster Monday. The first is Mark Madsen, a 6-9, 245-pound power forward nicknamed "Mad Dog" for the intensity he brings to the court. The other is Fred Hoiberg, a 6-5 shooting guard who was so popular at Iowa State it was said he could run for mayor.

The two signings -- Madsen for two years, Hoiberg for one -- continue the restructuring of the Wolves roster, one that will bear slight resemblance to last season's. It is possible that when the Wolves go to camp they'll have only three players -- Kevin Garnett, Wally Szczerbiak and Troy Hudson -- from last season.

The Wolves have traded for Sam Cassell, Ervin Johnson and, most recently, Latrell Sprewell. They have signed center Michael Olowakandi.

Monday's signings added grit and intangibles to that new collection of stars, especially in the case of Madsen.

He was a role player for the Lakers on two NBA title teams and established a reputation as a player willing to do a lot of the little things that don't appear in a boxscore.

"He has character and he has toughness," said Kevin McHale, Wolves vice president of basketball operations. In Madsen, McHale has added another player willing to take issue with anyone attempting to drive down the lane. "He'll put a body on you, be aggressive. He's a big, strong guy, which is something we wanted and needed."
