I began to look in depth at the Buffalo Bills' offensive line several years ago. Buffalo's line, at that point, included Melvin Fowler and Duke Preston. There was much back-and-forth (on another site, mind you) about Buffalo's centers. Some thought Fowler and Preston were just terrible, and some believed them to be serviceable, or even above average. People bickered back and forth and no one really attempted to back up their positions with any sort of data.
Frustrated with the endless recriminations, I sat down and began to analyze every lineman on every snap and created a rating system to quantify the effectiveness of the individual linemen. It served to give people a taking-off point for discussions about particular linemen, which allowed the conversation to move beyond he's-great-versus-he-stinks.
Over the past few years, several sites have begun to take a much closer look at offensive linemen. Brian, for example, recently linked a story from a site that rated Demetrius Bell the best left tackle in football. While I am limited to watching the very same game you are, these sites presumably have access to coache's tapes - tapes that provide better angles which allow for more precise judgments as to the performance of each lineman. Additionally, professional sites rate and compare linemen on all 32 teams.
I like looking at the line and will continue to do so simply because it is of personal interest. However, if the consensus seems to be that the professional sites are the way to go, then there may not be a need for me to take the time and effort to do weekly write-ups. I've attached a poll to get the pulse of the Rumblings community. I ask that people not take to the comments section to try to sway people one way or another; instead vote in the way that makes the most sense to you.
