A coach might see it as a time to play those bench-warmers who never get into the game, since it can't hurt at this juncture. The punditry have already moved on to speculations about 2016. I'd guess many of us politics-watchers are there too.
With regard to 2016, the conventional wisdom is that Republicans can no longer win presidential elections ... the CW is often wrong. For a two-term president to be succeeded by a candidate from his own party is uncommon, although possible. More typically in two terms a president demonstrates to the voters that a change is needed and they deliver one by electing the other party's guy. Shifting control is a part of the magic that is our political system.
Now it remains for the GOP to nominate someone whom the voters can imagine as President, not always the easiest task. Romney would have been a good president, I believe, but voters weren't sure about the Mormon thing. I see problems with Cruz, Rubio, Christie, Jeb, Perry, Huckabee, and Paul. Their problems are less severe than those of Clinton, but real nonetheless.
