Yesterday one of our readers @brettallred tweeted me a great article on Oklahoma State’s returning lettermen: Cowboys have smallest percentage of returning lettermen in nation. This tweet and article coincided with an email I had received earlier in the day from Keeper’s College Football Ratings whereby they gave TSE permission to republish their detailed report on FBS personnel lost from last season. 

The report has some great info on Offensive Starters Lost (OSL) & Defensive Starters Lost (DSL). It also breaks down, by position, the percentage of production returning from last season. They have all 128 teams on their site, but I have broken down the information by conference, and I have only included the the 5 Power Conferences in this article. 

Check out the Keepers site for a detailed explanation of each column.
