If watching is caring then yeah, I care at least somewhat. It's cool to see franchises like the Reds and Padres become relevant again. White Sox and Marlins too.
Having a 4 way race for the last wild card going into the last 2 games is pretty cool. I'm a Giants fan, and a fair-weather Mets fan, but I wish I had any confidence in either of them, and I have no confidence in whoever gets that slot and has to face the Dodgers.
Maybe it's NL West bias but I feel like whoever comes out of the top half of the NL bracket - Dodgers or Padres - will handle ATL for the NL pennant and go on to beat the Rays or Yankees or whoever.
