Not to bog down in the details, but he was only officially the GM after Jeff Diamond went to Tennessee after 1998. Obviously he had a lot of say on the draft etc. in a way no baseball manager ever would.No.
Denny was our best de facto GM the Vikings ever had.
If you believe post season is the be all end all, then no Gardy shouldn't be in the Twins HOF. But he was a damn good regular season manager, and it's a lot harder to make the play-offs in MLB.
His best managing job might have been 2008. They traded Santana and lost Torii Hunter to Free Agency. The opening day starter was Ramon Ortiz. Were expected to finish 4th or 5th in the division. And they still took the White Sox to game 163.
