I saw this too in the coverage of Miami-Indiana and Miami-Boston...every other day you read an article that asked "are the Heat done?", and a couple of days later, "is there anyone who can stop the Heat?"
but there is a legit parallel between Jordan's career arc and James's...both of them were the most unstoppable force in the NBA that took awhile to figure out how to win a title. Lebron faced the choker tag, Jordan was supposedly selfish and could not elevate his teammates. ironically, Kobe got the same criticisms as Jordan did after Shaq left and he struggled at first to win titles without him.
lastly, I dunno what adding Ray Allen does for Heat team chemistry...there is genuine hatred for the Celtics among the Heat guys, although to be fair most of it is reserved for KG, Rondo and Pierce. I suppose Lebron and Wade would say the right things and say as long as he can help, etc...but I still don't know.
