I would add that if the Phillies win tomorrow they'll be 6-0 at home in the playoffs. And also, while I don't think it means much, the Astros had a losing record at home this season, and are 1-2 in the playoffs. Even if the Phillies struggle, if they are down 3-2 in the series coming home they'll have a big chance to force a Game 7. That was not the case last year. I suppose you could say the 2-3-2 format favors them if they win one on the road first, even though it didn't work out that way last year. Having four home games only helps if you play them all.
But sure, yes, it's premature. I'm not too worried about Nola, I'm worried Kelly might do what Gallen didn't and pitch a serious gem. Can't get into another one like Game 3, gotta get a few runs on the board early. The crowd factor should be more insane than ever.
