The deal, which included a $130,500 signing bonus, will cost the Lions' rookie salary cap $268,000.
The first year of the deal will be worth $225,000, the second will be $305,000, with the third year bringing in $380,000. The gross of each of the three years are all rookie minimum base salaries.
Holt, 6-2, 208, was a second team All-America at his position and a semi-finalist for
the Jim Thorpe award given to the nation's top defensive back.
Holt started every game at free safety for the Wolfpack and recorded 100 tackles including 67 solo. What really raised eyebrows was Holt's penchant for blocking kicks on special teams. Holt totaled an eye-popping 13 blocked kicks over his career including four field goal blocks in 2001, tying the NCAA's all-time single season record.
The 23-year old is the younger brother of St. Louis Rams receiver Torry Holt.
Meanwhile, Detroit also inked undrafted free agent tackle Toby Golliday to an undisclosed contract.
At 6-1, 215, Golliday was an undersized but effective tackle for the Barcelona Dragons in NFL Europe. He is expected to try to make the team as a special teamer. Golliday played his college ball at Mississippi State after he transferred from Mississippi Delta Junior College.
LionsFans.com has also learned that Detroit has begun preliminary negotiations with each of their rookies. While nothing seems imminent, one agent told LionsFans.com that there is no rush.
"Training camp is still a few weeks away, so we aren't in a hurry," said the agent, who also commented that rookie negotiations across the league are very slow to develop.
