The Alabama football program has produced a number of NFL running backs over the past 10 years, but the latest export takes size and strength at the position to another level. 

Crimson Tide fans are already well aware of how powerful and devastating Derrick Henry can be with a football. The Heisman Trophy winner checked in just under 6-foot 3 and a staggering 247 pounds at the NFL Combine in February, but Henry still managed to run a 4.54 40-yard dash.

It's hard to put that size and speed into perspective until you see him standing next to his 'equals' at the position. During an autograph signing at University Mall on A-Day, Henry posed for a picture next to Green Bay Packers running back Eddie Lacy.

Keep in mind that Lacy weighed around 235 pounds last season. Even though he's apparently done a great job of losing weight this offseason, he's still a big dude. You'd never think that seeing this picture.

It's pictures like this that make Henry one of the most intriguing prospects in this year's NFL Draft. He's being projected as a second-round pick in most mock drafts.
