I also think the actual point that was being made regarding getting the ball after the half and viewing that as a 'turnover' was perhaps misstated a bit- getting the ball after the half DOES create the possibility that a team could effectively get two consecutive possessions, which doesn't happen in football other than following a turnover. There's no guarantee that deferring results in that scenario, however. But, I think the greater point is accurate- if, following the game play of the first half, you end up trailing and with the ball late in the half, you have the unique opportunity to cut into a lead by having the chance to score twice consecutively to get back into the game. I think what was misstated was that there is literally zero guarantee that you either A)score on either of the possessions, let alone both, and B)that you're the team with the ball late in the half. But, the opportunity for the scenario to play out is indeed there.
