Nick Chubb, Joey Bosa lead SI.com's 2015 Preseason All-America Team

Check out SI.com's 2015 Preseason All-America Team, a selection of the top players in college football.

One did a front flip into the end zone. Another took over the three most important games of his team's season. A third intimidated opponents and fans alike with his mere presence. Luckily for college football fans, this trio of players—TCU's Trevone Boykin, Ohio State's Ezekiel Elliott and Baylor's Shawn Oakman—returns to campus this season, as do an abundance of other stars. We've picked the best of the best to be honored as members of the SI.com 2015 Preseason All-America Team.

Perfectionism personified: A national star now, Scooby Wright not satisfied

Only three players earned unanimous selection to the first team from the ballots of SI.com's college football writers: Ohio State defensive end Joey Bosa, Florida State cornerback Jalen Ramsey and Seminoles kicker Roberto Aguayo, who returns to the preseason first team for a second consecutive year. The SEC comfortably earned the most honorees with eight first-team selections and 18 total selections. The Big Ten, Pac-12 and ACC all contributed four first-team members and 10, eight and seven total members, respectively. Colorado State stud receiver Rashard Higgins was the long Group of Five player to make the team.

Among individual teams, defending national champion Ohio State led the charge with four first-team selections (the entirety of the Big Ten's first-team members). Alabama and Ole Miss each earned three first-team spots, while Notre Dame, USC and Florida State all got two on the first team.

The complete first- and second-team rosters are below. For more preseason college football coverage, check out the SI preseason Top 25, games that will shape the playoff race and television media roundtable.
