First, the facts. Hester's 20 return TDs moved him past Deion Sanders on the NFL's all-time list. Sanders, of course, was inducted into the Pro Football Hall of Fame in 2011. Rod Woodson, next on the all-time list with 16 return scores, slipped on his gold jacket in 2009. Ronde Barber, fourth with 14 return scores, will have a very strong case when he becomes eligible in a few years.
That's fine company, but even Hester would admit he's an outlier in that group. Sanders was a dominant shutdown cornerback in addition to his return skills. Woodson's 11 Pro Bowl nods are the most ever for a defensive back. Barber was a five-time All-Pro cornerback and star of one of the greatest defenses in NFL history (the 2002 Bucs).
Barring a late-career production surge, it still feels like a stretch to put Hester in Canton. Then again, a lot of people thought Ray Guy would be on the outside looking in forever.
