A little bit of both. This is the last year for the Heat is mostly what I was saying somewhat cryptically. They are certainly as likely as anyone to win the title this year, but I think it'll be their last title or run at one. Wasn't sure why they are missing out on these signings (Indiana signed Bynum as much for his contributions as to NOT have him on Miami) although now it looks like they tried on Caron and he preferred to go to OKC.
You can't stay on top forever, teams that 3 peat have to play on fumes, its just scary because Lebron is on a path of destruction and D Wade has looked healthy.
