Darrell Thompson attended Rochester John Marshall High School, then played football for the University of Minnesota.
Marcus Sherels also attended John Marshall and played for the Gophers.
Thompson was a big, strong, fast, smart athlete who became a college star. The Green Bay Packers drafted him in the first round in 1990.
Sherels was an undersized walk-on at Minnesota who earned a scholarship and became a quality college player. He went undrafted.
Thompson lasted five years in the NFL. Sherels is about to pass him in pro football longevity.
Sherels signed with the Vikings as an undrafted free agent in 2010. He has spent his entire NFL at the bottom of the roster, knowing he could be released at any moment. At a listed 5-10 and 175 pounds, he has become an effective punt returner and willing utility player.
When the Vikings re-signed him last week, Sherels was set up to play a sixth season in the NFL.
As Sherels' mentor, Thompson is not surprised.
