In the course of moving on from DeAndre Jordan, the Mavs have already begun to address their deficit at center, signing Zaza Pachulia. But the only depth at the position at the moment is....oh. So help is still clearly needed.
With the NBA market void of many options at the moment, Mark Cuban has mentioned in interviews that his search for a center might take him overseas. With that in mind, here's some news/not-news: Cuban has begun following two international big men on Twitter: Augusto LIma, a 23-year old 6'10 Brazilian, and Salah Mejri, a 7'1 Tunisian who just turned 29. Both players most recently played in Spain; Lima for UCAM Murcia and Mejri for Real Madrid.
Lima is probably the more well-known of the two, having been on the prospect radar for some time. He went undrafted in 2013 but impressed at the Adidas Eurocamp.
