Pell's misdeeds were never made up by Galen Hall. When Spurrier came in, there were no scholarship reductions as a punishment. However, when the NCAA reduction rules went into effect, teams were allowed to "wean" their rosters. In other words, teams that had 95 players were allowed to keep those that they had on schollie, but could only add 25 per year, so for the first three years, most of the SEC teams had more players than Florida.
As a sidenote, it seems unlikely that a difference of 2/3rds of a game difference per year would be statistically significant.
