I also just had a few strange/disturbing/potentially funny thoughts .......
If the cap drops as expected ..... the Heat are going to be gathering up minimum salary players for the rest of the next 5 years.
There has been some talk about the Heat signing Z .... but could you imagine them dragging him up and down the floor in fast break mode? Really though, anyone else they try to sign is going to be less than an ideal fit. I do think it would be funny to hear about James grousing about his teammates allowing runs while he's on the bench as evidently happened while he was in Cleveland ......
Their best hope is that they hit with a 2nd rounder ..... but then I don't know if they'll then be able to re-sign that player? (What are the rules on re-signing a 2nd round pick if you're over the cap?)
Could you also imagine if the NBA and players agreed on a "hard cap" like the NFL has? No exceptions ..... no exemptions ..... play within a $60 million hard cap ..... and if you are over the cap, you have to move a salary to get back under. That could create an interesting dynamic within a 3 star team if suddenly, one of them had to go. This is the least likely to happen ...... but it would be funny.
In the back of my mind, I know that this teaming up of superstars is likely to be the greatest thing since sliced bread for Miami ....... but there are also a lot of things that could go really wrong. If something dod go really wrong .....I just hope that James is the one left on the court trying in vain to make it right.

(Not that I'm vindictive or anything)
