Bentil was drafted in the second round by Boston last year but was eventually waived in the preseason. He previously played for Fort Wayne in the NBA D-League before joining Xinjiang in China.
Cook went undrafted in 2015. He had a chance to join the Cleveland Cavaliers and New Orleans Hornets the past two preseasons but ended up being waived. He was named MVP of the D-League All-Star Game last weekend, something which may have caught the eye of the Mavericks.
The Mavericks had two roster spots after sending Andrew Bogut and Justin Anderson to Philadelphia in a deal for Nerlens Noel and waiving guard Deron Williams. (with reports from AP)
