Maybe, but I seriously doubt they can beat Toronto on the road. But having said that, the way things are lining up that would be in the Eastern Conference Finals, and I am guessing everyone would take that outcome right now given how things have gone this year.
There are a few parallels to last year to, I just checked and following a 4-game win streak to start 2018 they went 21-17 to finish the season. Granted, Kyrie was hurt, but I think you are seeing a lot of the same issues.
