It was an especially boring NFL Supplemental Draft this year. There was really no buzz going into the event since there were no noteworthy players eligible this year, and nobody actually ended up being picked.

Yes, all 32 NFL teams decided to sit things out for this year's Supplemental Draft. Four players were eligible to be picked, but now they are all undrafted free agents. This means that running back Traylon Shead (SMU), wide receiver Chase Clayton (New Mexico), defensive tackle Lakendrick Ross (Virginia-Lynchburg) and linebacker Darius Lipford (North Carolina) are free to sign with any team that sends an offer their way.
It's unclear if the Detroit Lions expressed any interest in Clayton, Ross or Lipford, but we know that they were one of the nine teams that attended Shead's pro day. With him going undrafted, they could sign him as an additional body at running back, but that position already seems to be set with training camp almost here.
By the way, with the Lions not making any picks this year, they still haven't added a player via the Supplemental Draft since 1982. That year, they selected defensive back Kevin Robinson by giving up a future ninth-round pick.
