I'm not quite sure what the Tampa Bay Buccaneers were thinking at the end of their loss to the Washington Redskins.
They had the ball already in field-goal position on second down with the ball on the Redskins' 33-yard line coming out of the two-minute timeout. In that situation you have to run the ball to either force the Redskins to use one of their last two timeouts, or if they don't, have the clock run down to the point where they wouldn't have much time left after the field goal is made.
Instead the Bucs chose to throw a pass that was almost intercepted and ultimately ruled incomplete. This stopped the clock, and after the Bucs did eventually kick a field goal two plays later the Redskins still had 1:42 left to work with after a touchback.
They made good use of that time, driving down to the Bucs' 24-yard line and kicking the winning field goal with just seven seconds left on the clock.
You can make the argument that as bad as the Bucs played in the first half they didn't deserve to win this game anyway—and I would have a hard time disagreeing.
Still, they were in position to win at the end and didn't, at least partially because of some dumb clock management at the end of the game.
