The Bull is a Cowboy Monday, March 5th, 2007 by Kevin Seifert Former Vikings QB Brad Johnson agreed to terms today on a three-year contract with the Dallas Cowboys, where he?ll back up young starter Tony Romo. Johnson visited Denver over the weekend but has a strong comfort level with Cowboys offensive coordinator Jason Garrett. Oh, and for those of you who forgot, Johnson?s nickname has long been ?The Bull? because of his strong-willed personality. http://www.startribune.com/blogs/vikings/?p=564
