By no means am I trying to defend Masterbather, but I think there is merit, to a point, about the Jays experiencing some really good fortune. The "luck" aspect of the team is that literally everything that needed to happen for the Jays to be at this point ... has happened.
All of the guys who needed to return to normal or better after down seasons....did. All the callups have basically delivered at the upper end of their percentile outcomes. SP has been largely healthy and when they did get hurt, the guys brought in exceeded expectations. All the starting position players that have been hurt... Varsho, Gimenez, Santander... none of their absences have hurt the team due to the depth guys stepping up an delivering. Think of all the nobody pen arms they cycled through early on to keep things going. Even those 2 brilliant starts from Easton Lucas (evened out by his following 2 turds... for sure). Little coming out of virtually nowhere to be utterly dominant in the pen.
In isolation, none of these things on their own is overly "lucky". One could reasonably predict Kirk and Bo rebounding .... Springer, maybe not to the point he has, but somewhat. One could predict at least somewhat of a Schneider bounceback, but again, not to the level he is at right now. Would anyone have predicted Loperfido running as hot as he has? Nobody could have predicted Lauer being what he has been. Same for Fisher honestly.
I think the contention that ALL of these happening at the same time is the fortunate part, not that any individual piece of the luck pie is or isnt probable.
