As the RB position changes, the criteria for HOF entry will too.
Agreed, but it's crazy that of the Top 80 RB's in rushing yards all-time, only 4 are active and Henry leads active rushers in 42nd...
To be fair, 2 of the top-5 all-time in career yards just retired in the last 2 seasons. Not that career rushing yards is a particularly good measure of quality of play.
I'll always argue Frank Gore was never at any point a truly elite RB, he just played forever. Every RB in the top-16 in career yards was better than the guy who is currently #3.
Obviously there will be another HOF RB. It is possible that receiving ability becomes more of an important factor than rushing ability though. Especially as more RBs like CMC or Ekeler, become the prototype. We just saw a guy along those lines go #12 in the draft, and that very well may be the future of the position.
