Offensive linemen and running backs were put through the gauntlet on Day 1 of drills at the NFL combine. Here's who helped their stock the most with their testing results.

Derrick Henry, RB, Alabama

There was a buzz in the weeks leading up to the combine that Henry was going to test well, and he more than lived up to expectations. At nearly 6-foot-3 and 247 pounds, Henry clocked in with an impressive 4.54 40-yard dash, while tying for the second-best broad jump (10 feet, 10 inches) and the fifth-best vertical (37 inches). While these numbers enter the freak-of-nature category, there are still concerns with Henry's change of direction and lateral agility based off his below-average times in three cone (7.20) and short shuttle (4.38). He has smaller hands (8¾ inches) and didn't always look natural, but he caught the ball relatively well. Overall, it was a good showing for Henry, who could potentially get into the top-40 mix before it's all said and done.
