It’s official: LSU QB transfer Stephen Rivers is a Vanderbilt Commodore, and he’ll be eligible immediately because he graduated from LSU in May.

Rivers will enroll this summer in Vandy’s Divinity School for his postgraduate studies.

Although Rivers is wildly inexperienced, he gives Derek Mason options. He’ll compete with returners Patton Robinette and Johnny McCrary, who battled all spring at the position, with neither being named the starter. Mason said this spring that Robinette brings a veteran and experience factor to the offense, while McCrary brings big-play ability. Now, Mason adds Rivers to the mix, and he is different than the other two under center.

Rivers is strictly a pocket passer with a lack of mobility and compares favorably to Zach Mettenberger. Robinette and McCrary are both dual-threat signal callers who can burn you with their arms or legs.

The biggest factor Rivers brings is another option. Depending on how well Mason perceives the offense to be or exactly what the offense needs as an identity (pocket passer or mobile quarterback), he has three different quarterbacks to choose from.
