Cut Jeff Withey and sign Bosh.
24. Someone signs Chris Bosh for the minimum
The most likely course of action as of now in this murky, sad situation, per sources all around it: The Heat wait until after March 1 to waive Bosh, so that he is not eligible to appear in the postseason for any team that signs him. At that point, Bosh's mammoth salary would vanish from Miami's cap sheet, freeing Riles to plop his rings in front of one or two stars this summer.
Bosh wants to play, and some team will absolutely sign him for the minimum -- even if it's just for this season. Bosh is still going to get all his money from Miami, and suitors will try to coax him into signing through 2017-18.
That is Miami's financial nightmare: The Heat spend a gazillion on free agents this summer, and Bosh plays at least 25 games elsewhere in 2017-18 -- at which point, NBA rules require his salary nestle back atop Miami's cap number. That could send the Heat flying into luxury tax hell. Miami hasn't found a middle ground that would allow it to waive Bosh and proceed with financial certainty. Bosh is under no obligation to provide them with one.
Meanwhile, signing Bosh on the cheap is a no-harm, no-foul move for a team with an open roster spot and the patience for a thorough medical evaluation.
