Appealing as this year's NFL Super Bowl matchup is—Patriot revenge, Giant resurgence, Brady legacy—it cannot and will not prevent me from me imagining the savory big-game matchups that could have been.
So what if the playoff gods did not deem them worthy? My mind can compensate for what reality fails to provide.
We're talking Harbaughs, Rodgers, Brees and the other alternate universes that never intersected with our own.
So basically we're talking wormholes...and football.
