If some team is willing to pay Thomas $18M on a one year, he should definitely consider and work his tail off next season to rebuild his value... and pray that he can as I doubt he will. After this season, his value has bottomed out. I’d be very surprised to see him get an offer for more than 3 years at a significantly low annual, like maybe $8-10M annually. But of course, never underestimate the stupidity of NBA owners and executives.
Personally, I think his NBA days are numbered. I think he’ll be out of the league earlier than expected, a once star that burns out unexpectedly in his early 30s like Arenas or Marbury did. Maybe he can become an overseas legend too. Considering his height and being the last pick in the draft, he’s actually done quite well to last in the league this long and actually play at the level he has.
