That would be ideal.
This would be amazing if he brought in Jabari Smith. Wow!
Don't know the answer about commits/letter of intent, and I didn't have time to read the whole thing (yet), but it sounds like the transfer portal was designed to remove the school release (that you reference). It refers to that in the past tense...
Previously in Division I, when student-athletes wanted to transfer, they had to ask their coach for permission to contact other schools. If the coach denied the request, student-athletes could make their case to the athletics director.
If permission was still denied, student-athletes could make the request to a designated campus administrator, such as a dean of students. If the request still wasn’t approved, the final step would be to appeal to a committee that consists of professionals on campus and other students.
Those who didn’t receive permission still could transfer but couldn’t be offered athletics aid at the new school.
