The promising thing is that atleast on the hitting side they're not doing this by having everybody hitting over their heads to the point you just know total regression will come.
Guys like Dingler and Mckinstry are almost certainly going to regress and even if Tork is for real he's likely not going to continue this pace but otoh Greene has room to improve as does Carp and Keith to offset that if and when it does come. Not to mention Vierling and Torres return and hopefully(not counting on it though) Meadows at some point.
I worry about the starting pitching depth when the inevitable happens but if Cobb can get healthy and Montero can get back to what he was last year that could help there. Not to mention every team lacks in that regard so as long as Skubal, Flaherty and atleast one of Mize/Jobe/Olson all continue to excel you can survive with a patchwork number 4 and 5 if it does indeed come to that.
One more potential bonus is that if we do choose to be buyers or need to upgrade somewhere we have the ammunition in our farm system to get it done as well.
