"Opt-in" schools can offer up to 26 full scholarships per team, eliminating the need to break scholarships into partial, 25% or 50% packages. This makes top-tier "opt-in" programs more attractive to recruits, as more players will receive full rides.
BU now has 14 forwards, 7 Ds and 3 goalies set for next season. If LD Xavier Villeneuve commits as is widely expected, that would bring the roster to 25, with one more slot to fill.
Also, BU will now be able to participate in revenue sharing with players. Especially important since starting this year, NIL used for solely "paying players" is now a thing of the past. NIL has to be tied to specific marketing and pass a NCAA clearinghouse.
One negative is that the max roster size is 26 players and that is frozen at the beginning of the season, If a player leaves the program or has a season ending injury, the roster spot cannot be replaced.
