The way the supplemental draft works is each team submits its list of whichever player — if any — it wants and in what round. If more than one team selects a player in the same round, he goes to the team with the higher draft order based on last year's standings. The team that ends up with the player forfeits its pick in that particular round in next year's draft.
For example, if the Dolphins select Unga in the third round and wind up acquiring his services, they would forfeit their third-round pick in the 2011 draft.
The Dolphins have taken one player in the supplemental draft through the years — USC defensive tackle Manuel Wright in the fifth round of the 2005 supplemental draft. We all know how that turned out.
About 20 teams were represented at a private workout recently held by Unga, and the Dolphins were believed to be one of them.
Unga rushed for 3,446 yards and 35 touchdowns over the last three seasons. He caught 102 passes during that span, including 44 in 2007 and 42 in 2008.
Unga made himself available for the supplemental draft after being thrown out of school and then having his appeal denied. He was dismissed from BYU for admittedly breaking the school's honor code by having premarital sex. His girlfriend gave birth to their son a few weeks ago.
While he could be of interest to the Dolphins, it's difficult to envision them spending a mid-round pick on the 6-1, 244-pound Unga given the depth they have at the position.
Perhaps a more likely target would be Price-Brent, who is given a chance to get selected in the sixth or seventh round.
At 6-2, 321 pounds, Price-Brent seems physically suited to play nose tackle in a 3-4, which is why he might be of interest to the Dolphins.
Price-Brent had 29 tackles, three sacks and three forced fumbles in 12 games in 2009. He entered the supplemental draft after being declared academically ineligible.
Castille and Emokpae, for their part, likely will not be drafted. Castille was kicked out of Nebraska because of a violation of team rules before ending up at Northwestern State. Emokpae earned his degree and decided to go to the NFL now rather than wait a year.
Players who are not drafted become unrestricted free agents.
Since the supplemental draft began in 1977, 38 players have been selected, with the list highlighted by Cris Carter, Bernie Kosar, Brian Bosworth, Rob Moore and Jamal Williams.
