Griffin was chosen
by Birmingham in the second round of the 2021 G League Draft.
Griffin was selected with the 22nd pick of the second round and is expected to add depth to the Squadron rotation. He went undrafted in the 2019 NBA Draft, but this will be his third campaign in the G League. He played for the South Bay Lakers in 2018-19 and for the Stockton Kings in 2019-20, though he only started a combined five games in that span.
