The XFL teams have released their 52 man rosters. I took a look at the colleges of each player who made the final roster of each team. I also broke down the NCAA conferences of each player by division.
It should be noted that there is one player who played NAIA, one player who played at Humbolt State which was an NCAA Division II school before dropping its football program prior to the 2019 season, one player from Globe Tech, one player from Grand Rapids Junior College and one player who played in Heidelberg, Germany.
The list begins with the colleges that placed the most players on XFL rosters and continues through each college followed by the conference breakdown.
