I haven't seen them mentioned yet, but Louisiana Tech has two players Mason previously targeted in the portal (they're a team based on defense and toughness, and it seems like a lot of the concepts they run are similar to Mason).
The first is
AJ Bates, a 6'3 PG Mason was in on before Okojie decided to come here. In the CUSA tournament, Bates was darn near unstoppable (think Long against Liberty, but setting up his guys with about 6 more alley oops while also scoring at will).
The second is
Avery Thomas II. For LATech, he played mainly stretch 4 (the Woodie role), getting 9 points and 7 boards per game. Thomas started in Juco, where he was a couple of free throws made short of the Durant line (he was at 50%/40%/81%).
There were several rumors about Thomas last year as the final piece (I may be misremembering, but Thomas was rumored... then Kaseem Watson.... then we shifted gears and brought in RPM).
