When former Georgia Tech wide receiver Darren Waller came out of school in an option-based offense back in 2014, he was largely an afterthought for many NFL teams. This despite standing 6-foot-6, weighing 238 pounds and running in the 4.4-range. After all, he started just 12 games over his last two seasons for the Yellow Jackets. His first few seasons in the NFL as a Baltimore Raven were largely unproductive, but Waller has become one of the NFL’s most versatile tight ends. We revisit our report on Waller from DraftNasty’s 2015 NFL Draft Manual.
