This is semantics, but I don't really consider 2016 to be an electoral college blowout, since 1980, 1984, 1988, 1992, 1996, 2008 and 2012 were wider EC margins. So Obama could suffer that size loss without being a Mondale type figure.
If he kept it close, he'd be a unique figure in time where he's young enough that he'd have 5ish more election cycles where he could plausibly run, and he was scandal free enough that it's plausible people would look back on the Romney economic gains as something he helped create a foundation for.
Edit: This isn't related to the OP question, but I just wanted to go back and see how close we could get to an Obama loss without major PODs. On election day 2012, Romney's voter turnout program, Narwhal, crashed and left them unable to do a decent amount of GOTV calls. Now, if you flip it, and crash OFA's VAN GOTV, you could probably suppress the Obama unlikely voters in Florida, Ohio and Virginia enough to flip them to Romney-- every other state was outside of the 4ish percent that field generally makes a difference in. In that event, Obama still wins with 272, so we'd need a few more PODs than a fluke event to get an Obama loss.
