The Vanderbilt Commodores (2-5) held off a second half rally to defeat Charleston Southern 21-20 on Saturday. The Commodores held an 18-10 lead at halftime and allowed 10 unanswered points in the second half. The Commodores used two different quarterbacks, with Johnny McCrary throwing for 169 yards, a touchdown and an interception on 10-of-16 passing.

Here are a five takeaways from the game:

1. Johnny McCrary is the only option left: Wade Freebeck suffered a hand injury early in Saturday’s game. McCrary entered in the second and played an efficient game, given his lack of preparation to take the majority of snaps. With Patton Robinette and Stephen Rivers also facing injuries, McCrary is the only option left, rather than the quarterback roulette we’ve seen from Vanderbilt throughout the season.

2. Jerron Seymour continues to be underutilized: Jerron Seymour didn’t have a single carry in Saturday’s game. After starting the season with an injury, Seymour has seen inconsistent results behind redshirt freshman Ralph Webb. On Saturday, Dallas Rivers saw the second-most carries with 47 yards and a touchdown on 11 attempts.

3. C.J. Duncan emerged as a No. 1 receiver: C.J. Duncan emerged as a No. 1 threat at wide receiver. Duncan recorded 119 yards and a touchdown on seven receptions. He was the one bright spot in an otherwise poor offensive performance.

4. Vanderbilt continues to make costly mistakes: Vanderbilt allowed a 17-yard blocked punt return for a touchdown with 0:38 left in the first half. This marked the fifth time the Commodores allowed a score with 0:40 or less remaining in the second quarter. The play swung momentum in Charleston Southern’s favor, which was evident in a 10-0 second half.

5. Commodores are still a mess: From top to bottom, Vanderbilt is struggling. The quarterback situation is in shambles and the skill positions are inconsistent. The Commodores continue to allow costly plays that should be avoidable. Vanderbilt is entering a much needed bye week and should address these issues moving forward.
