New Orleans Saints

Impact pick: WR Nick Toon (fourth) -- He's not overly explosive and will never be a big-play threat, but Toon is a very good route-runner who understands coverages and can adjust on the move. He's very savvy and will put himself in positions where QB Drew Brees can throw him open. Toon will adjust to balls and make tough plays, and with his hand-eye coordination and boundary awareness he'll be a huge help in the red zone. He could easily work his way into the No. 3 job as a rookie if he can put durability concerns behind him.
Intriguing pick: DT Akiem Hicks (third) -- Strange circumstances during his recruitment by LSU out of junior college led to Hicks leaving the Tigers and landing in Regina, where he simply dominated lesser competition with his sheer physical gifts. Hicks has size and heavy hands, and he moves well for his size. He is as raw as it gets, though, and needs to become more explosive. There are few rookies who stand to gain as much as Hicks from NFL strength/conditioning/nutrition programs, though the Saints likely hope he can spell NT Brodrick Bunkley at times while developing. If Hicks realizes his potential, though, he could become the heir apparent in the middle.

Top 2012 undrafted free agents

Scouts Inc.

A look at the 10 best undrafted free agents after the 2012 NFL draft:

1. Washington RB Chris Polk
A lack of explosiveness and durability concerns are likely the reasons Polk went undrafted. However, he displays good vision and balance, and is versatile enough in the passing game to potentially bring big returns as a free agent.

2. Troy G James Brown
Brown needs some development in terms of core strength and doesn't always play with consistent pad level. He lacks elite length to line up at tackle but has enough lateral agility to hold up on the interior in a zone blocking scheme.

3. Iowa State CB Leonard Johnson
A lack of size and ideal top-end speed are likely what scared teams away. Still, Johnson is a tough and instinctive defender who does not back down from challenges. He also possesses good ball skills and is willing in run support.

4. Virginia CB Chase Minnifield
Minnifield is one of the more instinctive cover corners in this class. In addition, he has solid ball skills and plays with aggressiveness. He didn't run as fast as teams would like, though, and that combined with microfracture surgery on his knee are the main reasons for his fall on draft weekend.

5. Tennessee RB Tauren Poole
Poole is slightly undersized and lacks juice as a runner. However, he possesses excellent vision and patience as a runner, and consistently gets the most from carries. Poole has a chance to go into a camp and earn a spot on a roster as a change-of-pace reserve back.

6. Furman CB Ryan Steed
Steed has adequate size, and is a tough competitor who is at his best getting physical and disrupting a receiver's release in press coverage. His lack of speed and struggles against upper-echelon competition might have scared teams away, but he's worth a look as a priority free agent who could develop into a solid reserve and special teams contributor on the back end of a roster.

7. Arkansas State S Kelcie McCray
McCray is a flexible, smooth athlete who shows good range in coverage. However, lack of instincts and strength, along with inconsistent tackling in run support, caused him to slip down the board.

8. BYU OT Matt Reynolds
Reynolds lacks elite athleticism and lateral agility, and is a bit heavy-footed. He has good size, though, and is fundamentally sound. He also has the versatility to line up at both guard and tackle to add depth to an offensive line.

9. Syracuse S Phillip Thomas
Thomas is undersized, and lacks elite top-end speed and overall range. However, he has excellent instincts and ball skills to capitalize when he is able to get into position. In addition, he takes solid angles and is reliable in run support.

10. Iowa OT Markus Zusevics
Zusevics lacks elite athleticism but has the strength, toughness and aggressiveness to develop into an adequate reserve at right tackle or move inside to guard.
