A: First, there are no guarantees with Tyler Johnson, as the clock continues to tick on his recovery from shoulder surgery, with Erik Spoelstra refusing to offer a timetable. Beyond that, the Heat are an injury at point guard away from being forced to scramble beyond Richardson. Goran Dragic's collision with referee Bill Kennedy in New Orleans showed how tenuous a proposition the Heat remain at point guard. That's why I not only believe consideration should be given to adding a point guard, but also perhaps more of a veteran than a neophyte such as Weber. Spoelstra previously had spoken of Josh McRoberts as a potential emergency ballhandler, but McRoberts hardly has been playing and hardly distinguished himself in Wednesday's start. And while Dwyane Wade and Justise Winslow can handle, that takes them away from what they do best. The shame is Andre Miller signing on so quickly with the Spurs, where he has become a post-buyout afterthought. Should Dragic or Richardson go down, the Heat would do well to have a veteran point guard as insurance, especially with the luxury of a pair of vacant roster spots. To that end, Luol Deng's absence also showed Wednesday that a defensive wing might help, as well.
