The transfer portal closed April 21, but college basketball programs continue to add to their rosters this spring.
Every Big Ten program has 10 or more scholarship players, but several programs still have roster spots to fill.
Here are some of the key numbers to know about the transfer portal’s impact on the Big Ten this spring:
