That being said I would vote for Dillon and that's it. He was every bit as good as Bettis, just played for a crappier team, with a crappier OL, and didn't get to face the Bengals defense twice a year.
The fact that people actually think Boomer is worthy shows the ignorance of this fanbase.
One way to look at it is that the Ring should obviously honor Pro Football HOF members and then people who came close or those that had special contribution to the team's history.
Dillon was close to the HOF. Boomer was never.
