METAIRIE, La. (AP) -- New Orleans Saints general manager Mickey Loomis says first-round pick Kenny Vaccaro and three other draft choices have signed four-year contracts on the eve of the first rookie camp practice.
Vaccaro, a safety out of Texas, was selected 15th overall in last month's draft. He is expected to compete for playing time right away at both safety positions and at nickel cornerback.
The 6-foot-5, 304-pound Armstead was drafted out of Arkansas-Pine Bluff. Stills was a standout wide receiver at Oklahoma.
Johnson played defensive end at Tarleton State in Texas and will line up as an outside linebacker in New Orleans' 3-4 defense.
