The New Orleans Saints bucked a recent trend of waiting until the last minute to sign their draft picks, inking four of their five picks to contracts Thursday evening.

With the team's three-day rookie minicamp set to open Friday, the Saints announced the signings of first-round draft pick Kenny Vaccaro, third-round pick Terron Armstead, fifth-round pick Kenny Stills and sixth-round pick Rufus Johnson. All the deals were for four years.

Defensive tackle John Jenkins, the second of the Saints' two third-round picks, is the only remaining unsigned draft pick.

Vacarro, the 15th pick overall in last month's draft, is the first first-round draft pick in the league to sign a contract.

The early signings almost certainly will guarantee the Saints won't have any holdouts for training camp.

In recent years, the Saints have been slow to reach contract agreements with their rookies. Although rookie contracts are slotted, leaving few major negotiating points, the Saints and the players' representatives haven't moved too swiftly to reach a deal.

Akiem Hicks, the Saints top draft pick last year, didn't sign his contract until June 28. And even that seemed to be an early signing by the Saints' standards.

In 2011, first-round picks Cam Jordan (Aug. 2) and Mark Ingram (July 30) didn't sign until after training camp had started.

In 2010, first-round pick Patrick Robinson signed his contract July 30, a day after the start of camp.

In 2009, first-round pick Malcolm Jenkins didn't ink his deal until Aug. 10 and missed the early portions of camp.

But the Saints, who were about $3.1 million under the NFL's salary cap before the signings, shouldn't have to worry about holdouts now.

Although financial terms of the deals weren't released, Vaccaro's contract is projected to be worth $9,465,782 and include a $5,234,328 signing bonus, according to sportrac.com.

Meanwhile, the team's rookies reported to the franchise's Metairie training facility Thursday and will take part in a three-day camp starting Friday. Here is the full list of participants in the rookie camp.
