There are layers to that discussion but I'm pretty confident that Presti isn't afraid of big deals. I'm pretty confident that they got PG cuz it was the best offer out there.
Vic and Sabonis was not nothing at all. Vic was solid and improving. Sabonis was a lotto pick the year before. I mean Presti turned a declining Serge Ibaka into SGA and a billion clippers picks and got Vic, Sabonis, and PG's services during the process.
Does Presti make some bad big deals? Yup. Does he prefer getting picks in deals? Yup. Is he just lucky cuz a player was good at recruiting... stop. Dude is a good GM.
