FOXBORO (AP) -- One day after sitting out the first round of the NFL draft, the New England Patriots got to work building their roster on Friday.
The Patriots picked outside linebacker Jamie Collins of Southern Mississippi in the second round with their first pick and the 52nd overall choice in the draft. They obtained the pick from the Minnesota Vikings on Thursday night, trading the 29th overall selection for four later draft picks.
The 6-foot-3, 250-pound Collins began his college career at defensive back and moved to linebacker in 2010. He had 21 sacks in his career at Southern Mississippi and led the team with 92 tackles last season.
"From the things I've heard about New England, there are a lot of pluses and very few minuses," said Collins. "I'm just ready to get in there and get started."
Soon after, with the 59th overall pick, New England tapped 6-foot-2, 203-pound wide receiver Aaron Dobson of Marshall. In each of his last three seasons, Dobson had at least 44 catches and 668 yards receiving. He had 12 touchdown catches in 2011.
His 24 career touchdown receptions tie former Patriot Troy Brown for fourth most in Marshall history.
"It's an exciting time, man. Just to have the opportunity to play in the NFL and play for a great team like the Patriots is just a blessing from the man above. I'm just excited to hit the ground running."
In the third round, the Patriots turned to Rutgers to find help for their secondary, selecting cornerback Logan Ryan with the 83rd overall pick -- which they obtained from the trade with the Vikings -- and safety Duron Harmon 91st overall.
The 5-foot-11 Ryan made 94 tackles and intercepted four passes last season. Harmon had 50 tackles and one interception last season.
The Patriots already have a defensive back from Rutgers, Devin McCourty. He was drafted in the first round in 2010 and moved from cornerback to safety last season.
When the draft wraps on Saturday, New England will have one selection in the fourth round and three in the seventh.
