23. Brandon Marshall
The unheralded Marshall was a fourth-round pick in 2006. He played extremely well for UCF but didn’t excite NFL scouts. He fell into Denver’s laps but had a quiet rookie season. However, things changed dramatically in his sophomore year as he exploded to life (via Bleacher Report).

Marshall had an impressive NFL career with five Pro Bowl appearances. Meanwhile, he led the NFL in receiving touchdowns in 2015. Remarkably, he never played in a single postseason game. It makes his legacy one of the strangest in the sport because he was a top player.
