Right now, Mizzou is at 74. If every senior (18) leaves and every other player comes back that means they could theoretically add up to 29 (I don't know that they can actually add 29). They are currently at 21 commitments if you include incoming transfer EJ Ndoma-Ogar. It appears the max currently left would be eight spots (understanding the math is likely to change)
