Problem is it's not just clock management, it's situational football. McD has actually gotten better with the clock, imho, since he's grown into the HC role and gave up play calling/DC duties. But he still makes some questionable situational, end of game decisions. The first being not declining the penalty to save time and leave it at 4th and 7, knowing a FG doesn't hurt us much. The other obviously being not having two calls ready for the first failed QB sneak. If you run that play, you have to be ready to go a 2nd time immediately.
I also didn't like the end of the half not going for it on 4th down and losing the chance for a double dip around the half.
That said, going for it on 4th against KC to put the game away was balls.
