A: If you are saying that James has been the Heat's most consistent power forward, I would agree, even with missteps like Thursday in Charlotte. But he's been even more consistent in another role, as someone who can spark the second unit, which he showed in his 22-point effort Friday in Boston. In a season when it has been difficult for the Heat to fill in the boxes beyond starting center and starting point guard, I think James' play off the bench has given Spoelstra a comfort level with the second unit that is difficult to move past. But there also is the layer of Johnson returning to the free-agent market in the offseason and perhaps eventually lobbying to get into the starting lineup. With Josh McRoberts out, and with Luke Babbitt and Derrick Williams as the other options, Johnson certainly has a case to move into the first five. As it is, the wheel of lineups again has stopped at Babbitt as the starting forward Thursday in Charlotte and then Friday in Boston.
