This is a partial fallacy. Points are no more important at the end of the game than they are anywhere else. The difference is at the end of the game time is of the essence, creating less chances to make up for mistakes and missed opportunities.
The key with timeouts is to MAXIMIZE their usage (I can't emphasize this enough). If per se, you are on the road and are with the crowd going nuts in the midst of a 6-0 and you have the ball trapped on the sideline, I'd hope Hoiberg (any coach) would have the presence of mind to call a timeout as that possession is critical. Meanwhile, having a stockpile of timeouts when having passed over several similar opportunities is nothing short of mismanagement.
While I'm not a Scott Drew fan (thee of having called several timeouts in the midst of his OWN TEAM'S runs), I don't think having no timeouts at the end of the game is an indictment....if they were used properly. It's the senseless usage of said timeouts and/or the failure to recognize their importance that's the bigger issue.
In today's case there really weren't a lot of instances (maybe one I can think of) where Fred should have called a timeout (in other words I though he did fine in that regard today). That doesn't mean however, that Fred isn't poor in this regard. It's an area (just like a lot of coaches) that he needs to work on.
This is a partial fallacy. Points are no more important at this juncture in the game than they are anywhere else.
