A lot more went right for the Jays than wrong. A lot more. Like, a ridiculous amount more. When 2 of your FA signings turn out to be a MVP and Cy Young candidate respectively, that's good luck. When your rotation stays healthy pretty much all season, that's good luck. No important player other than Springer missed time. The bullpen injuries involved Yates (signed him knowing he was hurt), Phelps (injury history), Chatwood (sucked after sticky stuff crackdown), Merryweather (lives on the IL), Borucki (not quite Merryweather but extensive injury history), etc, etc.
This is why prior to this September run this was looking like such a disappointing season. So much went right that it would be a shame if they didn't at least make the WC game. Thankfully they've gone on a tear since then and hopefully they end up making the WC game, but I don't think it's fair to even compare what went wrong versus what went right. Apples and oranges.
