The only second round appearance that I count is the Houston series, getting past the Clippers was 90% lucky break because of the other team's injuries.
The trajectory this team is on, is very similar to those 80s teams that always managed to just squeak into the playoffs and quickly bow out, but the team could always fall back on, "hey we made it!" and then wash, rinse, repeat year after year. This team looks close to maxed out in terms of potential. Maybe Collins will develop into a quality rotation player, but I don't see a star in the making there, Nurkic has mostly regressed to the same inconsistent guy he was for the Nuggets and I'm sure he can get marginally better over time, but I don't see a star in the making there either, and with the boat-anchor contracts they have in guys like Turner, and Meyers, they are going to have a very difficult time getting better in the next two years, which they absolutely need to do to convince Damian that they aren't just stuck on a treadmill.
This franchise looks like it's painted itself into a corner, and if they are serious about building around Damian and/or CJ before Damian has the power to decide where he'd like to go, it's going to take an incredible stroke of luck in the draft or some miracle trade to get them out of this holding pattern. So while I don't have a crystal ball, it doesn't take a psychic to see where this thing is probably headed (and it isn't to the Conference Finals or beyond).
