A: That is the exact opposite way that the Heat are looking at it. In fact, if that is Dorell's approach coming in, then he likely wouldn't be the candidate for the job. What the Heat are looking for is insurance, someone who could step in only if the current pieces in place aren't available. As it is now, Gerald Green and Josh McRoberts aren't playing, and that's with Tyler Johnson still out. What the Heat are doing is shopping for insurance policies, Dorell on the wing and possibly John Lucas III at point guard. The hope is the tight, eight-man rotation, given the absence of back-to-back games in the playoffs, will be what continues to move the Heat forward, as it has done since the All-Star break. But should someone go down or should someone suddenly prove ineffective, then there would be an emergency backup available. To be honest, if any of the players the Heat add at this point under the luxury tax have to become contributors, then something likely would have gone in a direction that already spells trouble. This is p-surance, playoff insurance, plain and simple, something the Heat now can afford under the luxury tax.
