7. Franco Harris
Even future Hall of Famers can have sophomore slumps. Harris won four Super Bowls in a majestic career but it’s easy to forget that he didn’t play well at all in his second year in the NFL. He scored just three touchdowns in year two as he struggled to make the same impact as his first year.

However, Harris rebounded and emerged as one of the best running backs in the league. He played in nine consecutive Pro Bowls which was a new record. Furthermore, he had six consecutive 1,000-yard seasons after the drop in his second year. That’s how you bounce back.
