Who doesn't love Fred Jackson?

The man who was once the leader of the Bills rushing attack, and is playing second fiddle to the stronger, more aggressive runner, CJ Spiller, is a great teammate.

Injuries and time have worn on him, but who doesn't want a player who brings his lunch pale to work every day and works as hard as Jackson? When you talk about players who are underrated in the NFL, the man from Coe College is at the top or close to the top of his list.

From the moment he stepped on the practice field for Buffalo, you just knew he would be great. Jackson was invited to training camp with the Bills in 2006 by then Bills general manager Marv Levy. By the way, Levy was an alum himslef of Coe. 

When he made his first career start against the Washington Redskins in 2007, he rushed for 82 yards while catching four passes for 69 yards in a Bills victory. Not a bad way to walk into the NFL.

While he has rushed for over 4,000 yards in his career and averages more than four yards a carry, injuries have been his nemesis. Having Spiller in the backfield has been a godsend, but it has also taken away carries and scoring opportunties for the veteran. 

Still, he is a player you want on your team.

If you look at Mario Williams, can know he is a player who can make an immediate impact on your team. The Bills knew that and once free agency started in 2012, they never let the former defensive tackle form Houston out of their site. Ralph Wilson and Buddy Nix got their man.

Williams was supposed to change the Buffalo defense. 

The Bills and their fans shortly realized that Williams, who is impressive with his size and speed, could not be a one-man wrecking crew. 

But when you sign a contract of $100 million and $50 million is guaranteed, it is expected that you are as talented as you are wealthy. Williams could never live up to those expectations. Williams had 46 total tackles, 10.5 sacks and 2 forced fumbles in 2012. But based on money and how the team perforned, his play and his talents are overrated for what is being asked.

With new teammates, a new coach and a new general manager in line in Buffalo, Williams will have every opportunity to impress the new regime and the fans.
