PITTSBURGH — Najee Harris went into the exhibition game Sunday against the Detroit Lions with a potentially serious foot injury, perhaps more serious than the Steelers had let on. So why did he play most of the first half in a meaningless game, a total of 28 snaps?
T.J. Watt nearly had his left knee blown out by a legal — yet dirty? — block by Lions tight end T.J. Hockenson early in the second quarter. So why, after hobbling off the field, did he return briefly for the next series?
Cam Heyward missed time during training camp with a minor lower-leg injury and didn't play in the first two exhibition games. So why was he on the field Sunday for most of the first half, a total of 23 plays?
