Wut? No, that's not how that works.
Because he's Kyle "Slo Mo" Anderson. This is comparing apples to raisins, which you know: "I know it's not a high profile player."
Butler has a player option below his market value. He's going to opt out to get more money (and maybe leave MN). Wiggins is a bad contract, and they should look to move it. KAT will get a max offer sheet soon (he can sign it in October of this year, IIRC). If not, he can be a restricted FA after this year, which gives MN the right to match any offer he receives (and they will). He can op to accept his qualifying offer to become an unrestricted FA after the 2019-20 season, but here's a list of significant players that have done that: {null set}. Shit, when someone as meh as Greg Monroe did it awhile back, it was a big deal because it is so rare.
Superstar players like KAT universally sign a second contract with their team (see Durant, LeBron, Carmelo, Kawhi, Wall, Irving, Dame, PG13, Butler, Westbrook, Curry, Wade, CP13, and many, many more), and their team offers them a max because when you're that good maximum salary has the effect of making you underpaid.
Narrator: He is.
