The 2021 college football season has reached the halfway point of the regular season. Conference play is among us and with a full season comes a critical opportunity for us to all review our perceptions of the players who will be making the leap into the professional ranks in the spring. The continued evolution of college prospects and their resumes is one of the most fun dynamics of the NFL draft process, and with half the regular season behind us, we at TDN are ready to reveal our first massive update to the TDN100. After spending the summer months studying the major prospects eligible for the upcoming NFL draft and setting initial expectations, we're now seeing the first big changes to our rankings. Some players have come out of nowhere to claim a high ranking in our personal top 100 eligible prospects via TDN100. Others have tumbled out of the ranks altogether. In all, there are 23 new additions to our top 100 prospects for 2022.
