Didn't realize this but the last year of AD's contract in 2020 is a player option, which he will likely decline. That means if Ainge deals for Davis next summer, he's only getting him for one season (unless Davis agrees to an extension which I don't think he will)
He also owns a house in LA and shares the same agent as Lebron. No way do I deal for Davis. Too much of a risk as it looks like he has LAKER written all over him.
I'd rather stick with the team we have and keep an eye open for other players. I know Ainge is on the hunt for transcendent players (Durant, Davis) but if the players either decide to go elsewhere or are unattainable, there's not much you can do.
