The chances of at least making a training squad are greater than usual this year.
For the first time, all 32 NFL franchises will be given an additional place in their practice squads specifically for those who have come through the IPP.
NFL franchises will be able to add IPP players to their practice-squad rosters at the end of the 10-week course, which is set to finish at the end of March.
Teams who have an IPP player on the practice squad will also be allowed to promote the player to the final active 53-man squad without taking up a space, up to three times during the season.
These rule changes have come at the best possible time for Rees-Zammit and the rest of the 2024 IPP group, as NFL franchises have little risk attached to taking a gamble on these players.
Wednesday’s Pro Day will be the best opportunity Rees-Zammit has to convince NFL scouts he has what it takes to make it in the sport.
The former Wales wing has previously said he is targeting a hybrid role in the NFL, combining the running back and wide receiver positions.
His speed and agility could also tempt teams into utilising him as a kick and punt returner on special teams, something he has said he “would love” to do.
