Depends how good i am. Am i Durant or Lebron level underpaid? (Ie woth 30, getting 20-25)? Or like a mythical Lebron level talent on a vet min contract? And by overpaid, do you mean Westbrook level (worth 20, getting 35, so unlikely to be able to afford to surround him with enough to win a title), or more like scalabrine (worth vet min, made 3.5 per year).
I guess, in order:
-Curry (supermax star, worth it, on title te
-durant/lebron (should/would be worth supermax, paid less, on a title type team)
-westbrook/wall (a star, but overpaid to point of making successful team building hard, probably never winning a title, but holy $$$$$$$)
-Scal on a bad team (lucked into 5 years of a few million more per year than worth)
- career vet min on a title team
