Fans can't play coach:
Its quite easy to sit behind a computer and critique coaches for their questionable decisions. Unfortunately, its also quite stupid. Coaches know how much a player can give, and how long he can give it. Are there efficient players who could use some more playing time? Sure. However, there is usually a reason these players aren't logging heavy minutes.
Whether its conditioning, high-risk of injury, problems with the playbook, or attitude, its clear that basketball is more then productivity. Its about the ability to sustain that productivity for long periods of time, and when fans haven't seen practices, medical tests, or trainer's diagnoses, they should avoid opening their mouths.
Unfortunately however, there is something terribly glorifying about sitting at home, looking at some numbers, and pretending everyone but you is an idiot.
And no, Drummond's injury wasn't a "freak accident". There are literally two reasons someone gets a lumbar stress fracture.
Predisposition (which the Pistons would have known about, hence Drummond's limited minutes).
Overuse, which again, hints at Drummond being physically unable to play heavy minutes consistently.
By the way, this isn't a post bashing stats. If someone wants to truly understand the game of basketball, they must thoroughly understand advanced stats and metrics. However, that isn't where the understanding stops. You then must supplement that knowledge with "subjective nuance", in order to understand the why, not just the what. Sadly, many fans today prefer to either throw the stats or "subjective nuance" out the window, which is similar to poking an eye out, and then trying to see.
