The Dallas Cowboys have the best under-25 talent in the NFL.

ESPN's Football Outsiders released their ranking of the top young guns around the league and the 'Boys came in at No. 1. The rankings were based off the number of games started in 2014, number of snaps in 2014, how the young player became a starter, number of first-team All-Pro and Pro Bowl selections, positional value, value added in the 2015 NFL Draft with a focus on premium picks, expected number of key contributors in 2015, and how a team develops and retains young talent.

Here's the breakdown for the Cowboys:

"Of the six first-team All-Pro players in the study, the Cowboys have two: left tackle Tyron Smith and right guard Zack Martin. Center Travis Frederick makes for a third Pro Bowl selection on the offensive line, and Dallas even snagged guard La'el Collins, considered by many to have first-round talent, after he went undrafted following unusual circumstances. Last season the Cowboys' offensive line ranked first in adjusted line yards and Joseph Randle could be the next running back to take advantage of one of the league's most stacked units. There are reasons for optimism on defense as well. DeMarcus Lawrence, who missed the first eight games last year with a broken foot, should be a Week 1 starter after notching a sack in both playoff games, including a huge forced fumble to clinch the win against Detroit. First-round pick Byron Jones should be the team's nickel corner, which is basically a starter in today's game. The Cowboys took a risk on Randy Gregory this offseason, but he's a very talented pass-rusher who should see the field on third downs. Linebacker Anthony Hitchens is also a likely starter after he showed as a rookie he was capable of playing each position in Rod Marinelli's defense."

Adding on, when you take away quarterback Tony Romo, tight end Jason Witten, and long snapper J.P. LaDouceur, the Cowboys have an extremely young roster. In fact, only eight players are 30 years or older.

If the Cowboys can have another successful season this year, they could be on their way to the start of a dynasty.
