Jenkins was a prominent prospect in the Hawks' draft plans. He was invited to the Hawks for two pre-draft workouts, a sign of obvious high-level interest.
The second visit, on Tuesday, was with Ferry in attendance.
"I like kids who can shoot," Ferry said. "He definitely can do that. ... He can shoot, and shooting is a big part of the game."
Jenkins said he made two visits to only one other team, Denver, so he thought he might be in Atlanta's plans.
"It was kind of funny because working out for them twice I kind of had an idea I might go to them," Jenkins said. "I wasn't sure. I knew they needed a perimeter threat and I know I can fill that void."
Jenkins will give the Hawks a much-needed 3-point threat. His 134 3-pointers last season tied the SEC record set by Vanderbilt's Shan Foster in the 2007-08 season.
Jenkins will play behind All-Star Joe Johnson but also could join Johnson and point guard Jeff Teague in three-guard lineups.
The Hawks expect Jenkins to fill the high-scoring role off the bench, much like former sixth man Jamal Crawford.
Drew said Jenkins doesn't slash to the basket like Crawford but is more of a pure shooter.
"This kid can go off the dribble but he can really (shoot) off screens," Drew said. "It's just a matter of him getting just a little daylight to get the shot off. He has range."
Atlanta hoped veteran forward Vladimir Radmanovic would provide a 3-point threat off the bench last season, but Radmanovic averaged only 4.5 points while making only 50 3-pointers. His playing time decreased through the season.
This was an important draft for Ferry and the Hawks, who have only six players under contract: Johnson, Teague, Al Horford, Josh Smith, Marvin Williams and backup center Zaza Pachulia.
