It's more of a logic exercise than an argument. And we still have an hour until game time. I think it boils down to risk. I don't like risk. If the Cubs win the division they are in. If they're fighting for a wildcard there is risk. However, in CCP's scenario they're in either way so it doesn't matter. I think things are going to get very tight down the stretch. The Mets and Phillies are playing much better baseball as of late. The Mets are playing good baseball. The Phillies are not. The Phillies have been treading water as long as the Cubs have. They hit their high water mark on June 8th, 13 games over .500. At the end of June, they were 5 games over. Today, they're 6 games over. There's plenty of risk either way. I also am looking to minimize the Cubs risk, and am even willing to throw away homefield to do it. If the Cubs play well (say, get to 94 wins or so) the only way they don't make the playoffs is if Milwaukee and St Louis both play really well and pass them. There's a statistically insignificant chance that 2 of the 3 of Philly, New York, and Florida can win 40 of their next 60 games. That's too good of a pace for too long for two teams in a division to do. If the Cubs play ok and win about 89 games (1 game under .500 the rest of the way), then the East could catch them. But Milwaukee and St Louis both have great chances to pass them as well. I think the Cubs would squeak out the WC in this scenario and probably lose the division by 3-4 games. If the Cubs collapse to 85 wins (9 games under .500 the rest of the way) they aren't winning either the division or WC. They have a better chance of winning the WC in this scenario, but they're likely staying home for the playoffs. Part of this logic is also what you think of Milwaukee and St. Louis. If you think Milwaukee is really good, you'd rather them sweep St. Louis. If you think the Brewers and/or the Cardinals are going to collapse in September no matter what, then a split would be good. The later it gets the more I believe that the former is closer to the truth then the latter, although the latter still has a pretty good chance of happening. I don't want the Brewers or the Cardinals in the playoffs. I want the Cubs in the playoffs. The only sure way that happens is to win the division. The surest way for that to happen is for the two teams behind them to beat each other up as much as possible so even when the Cubs lose one of the two isn't gaining ground on them. The closer the Brewers and/or the Cardinals are to the Cubs the less likely it is that the Cubs make the playoffs. When you win your division it doesn't matter what your record is compared to the rest of the league. That's not the case with the WC.
