My opinion:
1) Some of our message board members are obviously too young to remember Phil Hansen. He wasn't just a "nice player." He was a consistent pass rusher and one of the most dependable players in the team's history. Bennett may have been the flashier guy, but he absolutely wasn't as consistent as Hansen was. Hansen represented the Bills better than Bennett did, in my personal opinion.
2) Bennett and the Bills parted on bad terms in '98 (before the season); the Bills put a franchise tag on John Fina, and Bennett (too stupid to realize being franchised is actually not an advantage) said it was a "slap in the face" that they considered John Fina to be their "franchise player," and not Bennett. He did not go out as a "friend" of the team.
3) No one says the Wall of Fame has to go in order of how good a player is. It isn't a descending order of greatness. They aren't going to make a list of the best players, #1-20, and then just go down the list numerically. It's subjective. Just like the Hall of Fame.
4) The reason Polian hasn't been put on the WOF is because he has been a GM WITH ANOTHER TEAM. They aren't going to put someone on the WOF that is currently with another franchise. Now that he's passed it to his son, and once he distances himself from Indy, maybe he'll do so. Saban will never go up there -- NEVER. And while he was a great coach, let's not forget that he quit on the team twice. You have to factor that in.
I love Phil Hansen, and although Bennett was a great player for the team, Hansen was one of the best players on those Bills teams, and one of the best all-time Bills players. If you don't remember him, you either were too young to know who he was, or you weren't paying attention. My personal opinion.
