LB Troy Dye
Dye could play in a relatively big role for the Vikings next season. He falls on this list a bit, though, because of Eric Kendricks and Anthony Barr at the starting linebacker positions, barring anything unexpected.
After that, linebackers Eric Wilson and Ben Gedeon have shown to be decent players. Minnesota might use the nickel package quite often, but the third linebacker spot is still important. If Dye wins it, he could be a useful player.
