Let's breakdown each game.

Notre Dame (OH) at Shepherd | Noon ET

The Shepherd Rams are coming off yet another strong season in Shepherdstown, West Virginia. The Rams reeled off their second consecutive 13-1 season, landing themselves in at least the semifinals both years. It should be no surprise that Shepherd is projected to win the Mountain East.

There will be a new face leading the charge on offense. Senior Connor Jessop replaces 2016 Harlon Hill finalist Jeff Ziemba at quarterback. He hopes to keep the Rams' MEC winning streak alive and return to the playoffs. Shepherd hasn't lost in the regular season since 2014. The Rams have gone 20 straight games in the MEC without a loss. The last loss? A 35-34 defeat at the hands of Notre Dame College in South Euclid, Ohio.

Notre Dame College is just one of two teams to beat Shepherd in Mountain East play. Ever. The Falcons placed second in the MEC preaseason coaches poll, coming off their best season in program history. Two of the conference's best offensive weapons return behind an offensive line returning four of its five staters. This could be NDC's best chance to capture its first MEC title, and there's no better test than aganst the reigning champs.

East Central at Oklahoma Baptist | 1 p.m. ET

The transition, albeit a rocky one, is complete. Oklahoma Baptist begins its first season as a fully-affiliated NCAA program Saturday at home in Shawnee, Oklahoma. The Bison return 10 offensive starters which should help them take a big leap forward. Defensively, Oklahoma Baptist returns just one starter, however have some experienced players coming back as well.

East Central (OK) is coming off a disappointing season on paper, but it perservered through an injury-riddled season. They get a fresh start in 2016, with several new faces at key offensive positions. Oklahoma Baptist vs. East Central should be an evenly-matched game and a good test for both right out of the gates.

The Battle of the Mascot: Week 1

The Fighting Okra. The Boll Weevils. The Vulcans. Half the fun of rooting for college sports, is the pride in rooting for the mascot. Sometimes, they are a bit more fun than others.

Each week, we will dig deep and try to find the best mascot/nickname battle of the week. Week 1 had a GAC rivalry in a battle for Arkansas.

SAU Athletics

The Southern Arkansas Muleriders traveled to Russellville, Arkansas in a showdown against the Arkansas Tech Wonder Boys. The Muleriders were the preseason favorites in the GAC. SAU finished 9-2 last season, posting one of the best seasons in program history.

That didn't bother the Wonder Boys, as they pulled off the opening night upset, defeating the Muleriders 28-21. In a GAC full of fun nicknames, you can be sure that you'll see both again in an upcoming Battle of the Mascot.
