Sheldon has consulted with teams and leagues at the professional, olympic, collegiate and high school levels in North America and Europe.
In 1998, the Badgers led the NCAA in scoring defense (10.2 points per game) en route to a co-Big Ten championship and 38–31 Rose Bowl victory over UCLA.
Over Sheldon's five years in St. Louis, the Rams made the playoffs three times, including an appearance in Super Bowl XXXVI in the 2001 NFL season.
The 2001 Rams defeated the Philadelphia Eagles in the NFC Championship Game and advanced to Super Bowl XXXVI, where they lost to the New England Patriots.
[5] The 2001 season concluded the Rams’ three-year run (1999–2001) as “The Greatest Show on Turf,” considered by many among the top offensive stretches in NFL history.
The Rams beat the Mike Holmgren-led NFC West Division Champion Seahawks before losing in the divisional round to the Atlanta Falcons.
Sheldon also shaped the development of veteran linebacker Angelo Crowell, who in only 11 games logged 95 tackles, two interceptions, two sacks and a forced fumble.
Veteran Kawika Mitchell, whom the team signed as a free agent prior to the season, contributed 91 tackles, four sacks, two interceptions and 15 quarterback pressures.
With injuries taking a toll on his position group, Sheldon also helped convert strong safety Bryan Scott to linebacker, where in just nine games he totaled 54 tackles, two sacks and three quarterback pressures.
In Abdullah's first year as a starter, the former undrafted free agent led the Vikings’ secondary with 105 tackles, including three for losses, along with three interceptions.
In 2011, with injuries cutting short the seasons of both Abdullah and Winfield, Sheldon's attention turned to the development of inexperienced players, like third-year pro and former seventh-round pick Jamarca Sanford.
His 16 tackles in the team's opener at San Diego tied for second-most in a single game by a defensive back in Vikings history.
Following Abdullah's injury, Sheldon helped ready rookie sixth-round pick Mistral Raymond, who started the team's final five games at free safety.
