Coach  breaks down the dramatic changes transforming college football rosters, focusing heavily on the new 105-player roster limit and the massive impact of the transfer portal.

Using the University of Tennessee as a primary case study, we examine how modern programs are constructed in the post-portal era. Long gone are the days when a new head coach needed three to four years to rebuild through high school recruits or junior colleges; today's programs can instantly reload with experienced players.

We take a deep dive into the actual makeup of Tennessee's 105-man roster:

• The Veteran Presence: Only 18 players are in their final year of eligibility (roughly 17%), meaning a staggering 85% to 87% of the team has the potential to return for the next season.

• Youth and Experience: Over half of the roster (53 players) consists of either true freshmen, redshirt freshmen, or sophomores.

• Positional Breakdown: A closer look at the distribution of rotational players on both offense and defense, and how modern coaching requires players to produce immediately or risk losing their spots to the portal.
