The question

Every offseason the transfer portal moves hundreds of players up a level, from the Group of Five to the Power Five. Coaches and fans argue about whether production at the lower level carries over. This piece answers with data instead of anecdotes: does a player's PFF grade before the move predict the grade after it, and does the answer depend on position?

What I did

  • Collected and cleaned a dataset of roughly 530 players who moved from the Group of Five to the Power Five between 2022 and 2024, with PFF grades on both sides of the move.
  • Ran regression and correlation analysis by position group to see where the jump is hardest and where prior production holds up.
  • Built the visualizations and wrote the piece for a general college football audience.
