The transfer portal, in numbers we can actually see
Some programs rebuild from the portal every year and some almost never touch it. The difference is readable from their rosters, and it decides where a transfer should spend their thirty days.
What we measured
Across the rosters we hold, at least 4,435 players arrived from another college, read out of 59,306 entries that name a prior club or school. Every one of those figures is a FLOOR. Detection depends on how a school formats its page — a roster that writes "Coastal Carolina University" is readable and one that writes a bare town name is not — so the true number is higher than anything here.
The number that matters to a transfer
Of the 2,001 programs with enough readable rows to judge, 186 fill at least a fifth of their squad from other colleges. Those are staffs that sign college players every year, have processed the credits before, and read an email from someone already on a roster as completely normal. It is a shortlist to spend your window on — not the only schools available to you, which is all of them.
The same fact, two opposite meanings
A roster that is 40% transfers is a warning to a high-school senior — those are minutes going to older, proven players — and a green light to a transfer. Same measurement, opposite advice, depending entirely on who is reading it. Any tool that shows you one number without asking which of the two you are is not being careful with you.
