In late August last year, I wrote an article titled “Why 2018 Cowboys rookies may contribute more in their rookie year than most previous draft classes.” In the article, I looked at how much the 2018 rookie class could be expected to contribute to the Cowboys’ 2018 season in terms of snaps played, and concluded that the rookie class would play 12.1% of all offensive and defensive snaps, which would make it the third-best rookie class since 2008 - at least in terms of first-year snap counts.
The projections for the individual players were naturally off versus their actual snaps counts, but the projection for overall snap percentage proved to be remarkably close to the actual snaps: I had projected the rookies to play on 12.
