Nowitzki signs deal for $10 million more than expected.

Dirk Nowitzki has signed his contract with Dallas, and a person with knowledge of the deal said it’s worth more than the original agreement. The 38-yearold star who has spent all 18 of his seasons with the Mavericks signed a two-year, $50 million contract Wednesday — $10 million more than the deal struck before contracts could be signed. The person with knowledge of the contract provided terms to The Associated Press on condition of anonymity because they weren’t released. After playing for two years on a hometown discount at roughly $8 million per season, Nowitzki will be the highest-paid Dallas player at $25 million in 2016-2017. Nowitzki has said he would like to play 20 seasons. There is a team option in the second year of the deal.
