This is his last max the spurs know he’s not entertaining taking less
They absolutely should push him to take the same type of near max extension Domas got and I don't think Fox is in the position to say no. It's still a huge contract but since it isn't tied to 30% of the cap Domas's final year is projected to be 26-27% of the cap. Keep in mind Fox blew up his team to get there and they didn't have to give up much as a result, it's completely different than Fox having his homegrown team by the balls trying to retain drafted talent like we were in. There will be no shortage of players of Fox's ability willing to come be Wemby's wingman and they have to make sound financial moves if they want to leap OKC and Houston - and apparently now the Luka Lakers. They have a once a decade pre-anointed player and the expectation is rings.
also if Paul wants Wemby as a client and gets Fox to take team friendly terms I am sure that him bringing on other clients at a discount will be a selling point to Vic, who 100% will be getting supermax deals.
