No, he played 3 seasons at BU, so that leaves him one final season of eligibility. Him graduating in 3 years just allows him to go the grad transfer route which essentially guarantees immediate eligibility (do they even pretend that it has to be for a grad program not offered at the school they are transferring from anymore?).
This kid looks like a good fit to me; fundamentally sound, high motor, high basketball IQ, gritty, sneaky athletic, and just a gym rat who plays the game the right way.
