Not true, go watch more games. Why would you hurry your offense and take stupid quick shots to give your opponents more offensive opportunities?? Idiotic.
I watch multiple games and different teams from different conferences play almost every night, from coast to coast, so I see plenty of coaches approaches to finishing off games. Your best coaches keep attacking, period, unless you are under 2 minutes, and have a very comfortable lead where you know they can't catch you before time runs out.
Who said anything about "hurrying your offense and taking stupid quick shots"?
Running the offense that got you a lead has nothing to do with what you just posted. Most coaches will try to build a big enough lead to actually get their bench players some real game experience.
There is a reason we never have anyone who can come in off the bench and look like they have ever played in a real game. It's because they haven't.
Playing to not lose at the end of the game is a chicken crap move by a coach in my book. But that's just me.
