Of course, we probably shouldn't expect young Markelle to be taking over games any time soon, but any edge helps, and should add to Tatum's mental database of 76ers' starters (he spent a fair amount of time working out with friend and Philly big man Joel Embiid this summer, with some memorable trash talk).
Are the Celtics ready for a real challenge from their reborn Atlantic Division rivals? Are the 76ers for real this season after losing key depth over the summer? Is Markelle really ready for prime time? How about Hayward, speaking of guys not shooting much last season? How will the tone be set for the coming season?
