He gave Kanter $70 million and Oladipo $80 million which are both awful contracts. Not to mention giving Kyle Singler that contract. I don't see how you can point to those offseasons objectively and be happy with the process or the results.
It speaks volumes to how amazing this offseason was considering he great returns for players that weren't really valuable.
He didn't 'give' taht deal to Kanter. He matched Portlands offer. He didn't want to lose Kanter for nothing. In hindsight that might have been the best option. Oladipo had plenty of value IMO. I think he is a solid #3 options on a good team. Guy was a high end 3 and D guy as his 3 point shooting was improving. In a year or two I think he will be considered one of the 5 best 3 and D guys in the league.
But - that lineup I posted above would have been the best team in the league hands down and Presti would have been considered a genius along with a multiple championship executive.
