Tennessee running back Jalen Hurd and Alvin Kamara give the Vols a dynamic duo in the offensive backfield.

Most fancy the pair as a "Thunder and Lighting" type, with Hurd being the bigger, stronger back and Kamara being the faster, shiftier runner.

Hurd posted a short workout video to Instagram that shows he has plenty of "Lightning" to go along with his thunder.

Check it out.

Hurd has rushed for 2,187 yards in his career and is on pace to become the program's all-time leading rusher. At 6-4 and 240 pounds he is certainly a load to bring down, but in 2016 it looks like he may not get caught from behind, either.
