Truth is, none of us know what's going to happen, as there are too many unknowns. Do league / team officials already know what the NBA is willing to accept on issues such as a hard/soft cap, max player/team salaries, rookie contracts, the number of grandfathered contracts/team, etc. Only then, can anyone, including BC, really predict what the raps should do.
My guess is that no one has a clue at this point, so a conservative stance would be to keep the team's financial flexibility and not take on long-term contracts... unless those long-term contracts come with hard to pass up young talent.
If a hard cap does come in, and teams need to shed salary, there may be some really good talent available to create a good team. Tanking now, and setting yourself up to get a number 1 pick while maintaining significant financial flexibility brings us right back to where we were when BC was first hired. That would suck, but, I'd rather be there, than where we are now.
