Alvin Kamara will see Tide-Vols from both sides

As AL.com's Michael Casagrande mentioned in his Tuesday story, it's not unheard of for a player to switch sides in a rivalry.

That's what Tennessee running back Alvin Kamara will do this season after initially starting his career at heated rival Alabama. Following a year away from the Crimson Tide, Kamara was one of the nation's most coveted junior college running backs when he elected to join the Volunteers earlier this year.

He should immediately form one of the SEC's most lethal backfield duos, running alongside star sophomore Jalen Hurd.

We've seen some of this among coaches in the SEC in recent years. Will Muschamp played at Georgia and has since coached at both Florida and Auburn – arguably the Bulldogs' two top rivals. Georgia's new offensive coordinator Brian Schottenheimer was once a Florida quarterback. Lance Thompson has jumped between Alabama, Tennessee and Auburn in just a few years' time. And just this offseason John Chavis left his post as LSU's defensive coordinator to take the same job at Texas A&M, and then his close friend Kevin Steele left a job at Alabama to take over Chavis' spot at LSU.

It's more unique with players, which is what makes the Kamara case so intriguing. Alabama will be fine at running back with Derrick Henry taking over as the starter, even if the Tide's loaded 2013 running back class is now down to just Henry following the departures of Kamara, Tyren Jones and Altee Tenpenny.

Tennessee, however, could become a much more dangerous team with Kamara adding another weapon for Butch Jones' team to utilize.
