if it all goes down, only thing the Heat fans should worry about is filling out the roster. It's looking more and more likely that Bosh will be a sign and trade, and sounds like the Heat would give up Beasley, Chalmers, and a resigned Joel Anthony.
If all that happens, it is not impossible to still build a team. I think the Heat got 3 guys in the second round that could easily be rotation guys in the NBA (with Butler having a chance to be something really special if he can return from his injury). Combine that with some of the UDFA's like Manny Harris, Scotty Reynolds, and Sheron Collins. Plus guys whove been good in the D-League/Overseas looking for teams like Joe Crawford, DeVon Hardin, and Derrick Byers, you can put together a good team.
Just because a player wasn't drafted or isn't in the NBA right now doens't mean that they aren't NBA caliber players.
Just read the Heat have reached out to Mike Miller for a 5 year deal that is either full or close to full MLE with a midnight deadline. Now that would be a huge pickup too because MIller is a great spot up shooter, but can also create his own shot if he's coming off the bench
