According to many sources, including Tim McMahon of ESPN, Mark Cuban loaned J.J. Barea the Dallas Mavericks team plane to help transport food and water to his home in Puerto Rico. Puerto Rico was hit horribly by a series of hurricanes that went through many islands south of Florida over the last few weeks, most notably from Hurricane Maria, a category 4 storm.
Barea has shown nothing but pride and love for his Puerto Rican heritage from the time he stepped on the court in Dallas and continues to hold true to his roots. Despite a lack of involvement from the US government, individuals like Barea have taken their time and efforts to get down there and help out with anything they can.
