I'm not so pessimistic.
let's state Cap will rise to about 80 mlns.
There are plenty of options:
- If Splitter turns out to be a good C in our system (few doubts) and will be healthy (many doubts) there's the possibility to trade Millsap;
- If Splitter turns out to be a good C in our system (few doubts) and will be healthy (many doubts) we can trade Horford in a sign'n'trade;
- If Splitter turns out to be a good C in our system (few doubts) and will be healthy (many doubts) we can trade him to teams looking for future cap space;
-We can trade Teague;
-We can trade cheaper players to create cap space, and go for a FA.
I think this team looks like the pre-Harden Houston: a team with great cap flexibility, many assets, good young players (actually just Dennis), all the draft picks and, thanks God, not in the place for tanking.
The Rockets were just waiting for a big free agent to sign with them, and they had their Harden. Let's see "what happens to us".
