Vince Wilfork's contract status will be a top issue for the Patriots. (Bill Greene / Globe Staff)
Sixth in a series of daily position snapshots leading into Patriots training camp, focusing on the defensive line:
|PERSONNEL & PROJECTED DEPTH CHART||Ends: 1) Richard Seymour; 2) Ty Warren; 3) Jarvis Green; 4) Mike Wright (also an option at nose); 5) Le Kevin Smith; 6) Myron Pryor (possible option at nose tackle); 7) Darryl Richard; 8) Steve Williams. Nose tackles: 1) Vince Wilfork; 2) Ron Brace; 3) Titus Adams.|
|TOP QUESTIONS||How does Brace, one of the team's second-round draft choices, adapt to the nose tackle spot? Is Warren fully recovered from double groin surgery in the offseason? Are there any lingering issues with Vince Wilfork and his contract situation? Will Pryor (sixth round) or Richard (seventh round) show enough to push veterans Green and Smith for roster spots?|
|DID YOU KNOW?||Richard Seymour led the Patriots with 8 quarterback sacks in 2008. ... Ty Warren's contract extends further than any other player on the roster (2013*). ... In 2007, Vince Wilfork was named one of the 100 greatest players in the history of Florida high school football by the Florida High School Athletic Association. ... Coming out of high school, Mike Wright's only offer to play football was at Division II Ashland University. ... Jarvis Green is the only Patriots draft pick from 2002 still on the roster. ... While attending Burncoat High School, Ron Brace won the Massachusetts state shot put title in 2003 and 2004.|
|NFL PERSPECTIVE||Longtime NFL coach Dom Capers spent the 2008 season as a Patriots special assistant and when assessing the team's 3-4 scheme upon his departure he said in a Boston Globe interview: "One of the things that's obvious is that you're going to have outstanding front people, with their down linemen up front. They're very, very good players and to me that's where it all starts." The strength and athleticism of the defensive line is the foundation for the Patriots' 3-4 scheme, and the group provides flexibility for scheming. For example, in some situations last year, the Patriots would play a 4-2-5 nickel package against base offensive personnel and rely on four down linemen to play strong against the run. So in those situations, even though the Patriots were lighter in the box, they still often held their own. The Patriots' line is one of the best in the NFL.|
|FUTURE||Wilfork, Seymour, Green and Smith have contracts that expire after the 2009 season. Wright, Brace, Pryor and Richard are all signed through 2012, while Warren is signed through 2013.|
* TE Chris Baker's contract technically extends to 2013 but a signficant option bonus payment in 2011 essentially makes it a two-year deal.
