247Sports has released its second annual preseason All-American Team, opening up voting to its vast network of team-based publishers and reporters. The team is listed below in the form of three graphics, weaved in with our five biggest takeaways.

1) Barkley vs. Guice will be one of the hottest debates of 2017

If you read the replies to any tweet about Saquon Barkley or Derrius Guice, you're guaranteed to find LSU and Penn State fans duking it out over which running back is better. Last year, we saw a similar dynamic between Myles Garrett and Derek Barnett and it appears as though Barkley-Guice is going to be one of the hottest positional supremacy debates of 2017. Unlike last year, when there were five or so running backs with legitimate claims to being the best back in the country, Barkley and Guice stand head and shoulders above peers. The only other backs in the country to receive votes in this poll were Nick Chubb and Royce Freeman. Guice received the most votes for an offensive player, making him the second-most popular overall choice after Derwin James.

2) We have an upset at QB!

Lamar Jackson is the defending Heisman winner and just last week was named the best player in the country per our College Top247 rankings. But he'll have to settle for second-team honors for our All-American team, which is selected by a wider pool of voters, who decided Darnold — by a margin of one vote — was the most deserving quarterback. Jackson's stats were more absurd in 2016 (51 total TDs, 5,114 total yards) but Darnold was close as a passer: More scores, better completion percentage, better QBR, better QB rating, and just below Jackson in yards-per-attempt and interception percentage. Darnold finished the season better, making the Rose Bowl his personal coming-out party — 453 yards, five touchdowns and one of the prettiest passes you'll ever see — while Jackson sputtered down the stretch. Projecting towards the coming season, both lose a good amount in the passing game, though Darnold's USC Trojans reload with a higher-rated incoming crop of receivers than Louisville. Given that plus his year-end trajectory, it's totally reasonable to have Darnold as the first-team quarterback.

3) Cornerstone players lift the Big 12

The Big 12 is generally perceived as the weakest Power 5 conference, and that's not without merit: Twice it's been left out of the College Football Playoff, it's the only conference to not have had a team advance to the title game once in the playoff, and the most recent NFL Draft was humiliating. Fourteen Big 12 players were drafted, the fewest since the conference's 1996 inception. And while the Big 12 still only landed three players on 247Sports' preseason All-American team, the thing that stands out is that two banner programs — Oklahoma and Texas — provide the two offensive tackles, Orlando Brown and Connor Williams. That's a position the NFL continues to value in the draft and, sure enough, Texas' Williams is a projected top-5 pick next spring, and Brown doesn't figure to be too far behind.

4) Group of 5 crashes the party

Ed Oliver and SMU wide receiver Courtland Sutton give the American Athletic Conference two players on our All-America team, and it's historically unusual for Group of 5 players to be getting this much love in the preseason. Over the past five years, only two non-Power 5 players have been anything close to preseason consensus All-Americans: Colorado State wide receiver Rashard Higgins (2015) and BYU linebacker Kyle Van Noy (2013). Sutton is a hot name for the 2018 NFL Draft, while Oliver — the No. 6 recruit in the 247Sports Composite for the class of 2016 — is a sophomore, so he'll have a chance to be back here in 2018.

So does this signify anything meaningful? It might be an indication that the AAC is closing the talent gap that keeps it in the Group of 5 instead of the Power 5. It might be that Group of 5 teams have always had this kind of talent and it's just easier to watch Houston and SMU games in 2017. Or it might be that two is still a pretty small number and we shouldn't read too much into this.

Either way, it's pretty neat!

5) Bradley Chubb? More like Bradley Snub.

N.C. State defensive end Bradley Chubb is the No. 14 overall player in 247Sports' College Top247 and yet he only received one vote in our All-America balloting. So what gives? Last year's FBS sack leader Harold Landry fairly occupies one defensive end spot and there's nothing wrong with choosing former top recruit Rashan Gary at the other; though you can't deny that Gary's recruiting stature and large-market affiliation greatly helps to give him the edge over Chubb in the minds of voters. On one of the best defensive lines in college football, here's to hoping Chubb begins to receive the national recognition he deserves.
