The best way to measure which conference team has the best talent on the offensive line is to evaluate the "predicted two-deep roster" with the most reliable source for player evaluation. Rivals rankings are the most reliable ratings of player talent level.
Now fans of teams who don't have the stars will knock the stars. But stars are stars.
This is not a measure of how squads play as a team, or who has the best coaching. It is a quick look at talent. Rivals rankings are important because more 5-star players are drafted into the NFL than 3-star players, and higher-rated players are better playmakers. That is why coaches recruit 4- and 5-stars.
Each team's 10 players on the predicted offensive-line two-deep roster can have a possible 50 points. That would be 10 players, all with 5-star ratings. But no team has that level of talent. For instance, Oklahoma has one 5-star player, five 4-star players, three 3-star players and one unranked player. That equates to 35 total stars. Oklahoma, perhaps the No. 1 team in college football, is a good benchmark at 35 points.
If your team does not have highly-rated players, no whining—there will always the rich and the poor.
