Professional career
Chicago Bears (first stint)
Schwantz was signed as an undrafted free agent by the Chicago Bears after the 1992 NFL draft. He was waived in August and signed to the practice squad. On December 25, he was promoted to the active roster to play in the season finale against the Dallas Cowboys, where he made one special teams tackle. On August 30, 1993, he was released after preseason and signed to the practice squad. On August 28, 1994, he was traded to the defending Super Bowl champions the Dallas Cowboys, in exchange for a sixth round draft choice.
Dallas Cowboys
In 1994, the Dallas Cowboys traded for Schwantz because they were thin at the linebacker position and because he knew their defensive system, having been coached by Dave Wannstedt, who was the team's defensive coordinator before moving on to the Chicago Bears. He was declared inactive for the first 9 games. He finished with 4 defensive tackles, 5 special teams tackles and was a part of the Super Bowl XXX winning team. In 1995, he continued his development, registering 23 special teams tackles, 15 defensive tackles and one pass defensed. In 1996, he set the franchise's single season record with 32 tackles on special teams and was named to the Pro Bowl as a special teams player. In 1997, he was declared a restricted free agent at the end of the season and although he was seen as a valuable player, the Cowboys had serious salary cap problems and could only tender him a qualifying offer at his original undrafted signing. On April 14, the San Francisco 49ers signed him to a four-year offer sheet for $2 million that included a $600,000 signing bonus, that the Cowboys chose not to match and did not receive any compensation.
San Francisco 49ers
In 1997, he registered 18 special teams tackles with the San Francisco 49ers. He was cut on August 25, 1998, after the team decided to keep two younger linebackers.
