Dirk Nowitzki has stated he would like to re-sign in Dallas and possibly take a pay cut to help the team bring in more talent.
“In the summer I will be free agent and likely extend the contract for two or three years” said Nowitzki in an interview with Sport1. “As long as the body supports me, it is still fun to play basketball. After the new contract I will be 38 or 39 and I will probably stop."
If Nowitzki gives the Mavs a big discount like $10 million per season, they'd still likely have enough room to add a max player, although it would mean renouncing the free agency rights to Shawn Marion and Vince Carter.
