NFL scouting combine: Bo Jackson, J.J. Watt among most head-turning performances

Each year, NFL draft prospects descend on Indianapolis looking to make their case in front of scouts, general managers and coaches. How these prospects perform in tests of speed, strength and agility can have a profound impact on where they land in the draft.

Here are players who had dominant combine efforts, and saw their draft stock improve as a result.

1. Mike Mamula: Combine visionary

1995 draft: First round (No. 7 overall), Philadelphia Eagles

Mamula was a rarity back in the mid-1990s: a prospect who trained specifically for the drills of the NFL scouting combine. His performance — including a reported 40-yard dash time of 4.58 seconds, which was especially incredible for a defensive end prospect at the time — vaulted Mamula atop the first round of the draft, and he remains a cautionary tale for NFL teams to avoid being romanced by impressive combine numbers.
