I'm not aware of a deadline for the super seniors to make a decision. As has been the case for several weeks, Mizzou's five seniors are not expected back in any capacity. Now, if Dru Smith or Tilmon wanted to play another season at Mizzou, I would think the staff would gladly take them back. But that's not happening as of today. I would not be surprised if at least one more player on MU's roster enters the portal. Here's how next season's roster stands right now:
Freshmen (five): Anton Brookshire, Trevon Brazile, Yaya Keita, Kaleb Brown, Sean Durugordon.
Sophomores (one): Jordan Wilmore
Juniors (two): Kobe Brown, Amari Davis
Seniors (three): Javon Pickett, Torrence Watson, Ed Chang
Now, keep in mind, the 2020-21 season did not count for eligibility, so players listed above as juniors are essentially sophomores eligibility-wise for 2021-22 and the seniors are juniors.
That's 11 players. That leaves room for two more additions. From what I'm hearing, Mizzou plans two more transfers whether or not another player enters the portal. Martin is OK sitting at 12 scholarships for next year again, one short of the maximum.
