If they do this deal, I wouldn't be surprised if it includes a non-guaranteed option for next season. Miami may just be interested in getting an early look at him for next season.
Obviously he's not going to be on their post season roster, but techinically he can't right because he was signed to late?
So then I don't believe it's a block against the C's.
Since he was waived by the March 1 deadline, he's eligible for the Heat's playoff roster.
