Speaking of Rashard Mendenhall... We continue the streak of great Illini running backs with the Steelers back at No. 11 on this list.
Mendenhall is a player who is still establishing his legacy in the league. But his talent, statistics and play in huge games are the factors that moved him up so high in this ranking.
Some may argue that this spot is far too high for a player who has only came into the league in 2008, but I believe that he is an elite talent who is only going to get better as he moves into the prime of his career.
It's that potential that puts him above some of the more decorated players who came before him on this list.
To me, the possession of a Super Bowl ring is what defines greatness.
And having the ring is a theme that resonates throughout most of the players on this list. It's one of the major contributors to making these players "the best ever," and Mendenhall is a part of that club with his Super Bowl XLIII ring.
On top of that, his stats in only four years have been downright awesome.
In his rookie season, he was only able to achieve 58 yards on 19 carries because of a devastating knee injury that put him on the IR list.
But since that season, he has been unstoppable, averaging 1,103 yards and 10 touchdowns per year.
The Steelers have been quietly moving away from the ground game in favor of Big Ben and his team of speedy receivers, but Mendenhall has made the most of his opportunities.
It is that consistency that propelled him to the No. 11 spot in only four short seasons.
