At one point in the game, Lowry had played over 20 minutes, had taken no shots, and was almost +10.

This is a head scratcher.

I honestly did not watch the game, but for those of you who did, can somebody explain what Lowry was doing on the court the entire time and why he was left in for so long despite not taking any shots?

Was just just making hustle plays? Leading by being a coach on the floor? Pulling a Marcus Smart? Or do the Heat just not have any point guards because they are still waiting on that call back from Portland on that Dame trade? ;-)
