50/50 that Celtics land a 32-year-old Dwight Howard in 2018. And I'll say 70/30 that, barring that, they sign the 37-year-old Howard in 2023.

I guess some people are better at thinking big that others.
After all who would have ever thought two years ago that Wade and Lebron could ever share a basketball to win.
And who would have ever thought someone could pull off two trades and land Garnett, Ray Allen, to go with Pierce.
Crazy. Just Crazy.
Well, there were a fair amount of people who thought LeBron would go to Miami as soon as LeBron said he was going to switch his # this season from 23 to 6..as 23 has been retired in miami for some time. I wasn't one of those prophets...but they existed.
And there were those who thought KG was coming to Boston well before he did, even after he said explicitly he wouldn't.
But the thing is..you gotta look for key items. Assets to attract (Rondo+who knows), cap space (we'll have it as long as KG and Ray don't re-up)..I mean, its not infeasible, I just don't think it is remotely likely. If it was next year, and we were coming off a deep finals run, even a championship...I'd bite. If we had assurances (which we won't until after the finals next season) that KG, Ray, and Paul would be back in a form that resembles their play this season, but at vet min contracts..I'd say it was likely.
But for all those things to happen in two seasons, I just don't see it.
