I don't really think it's a must that both Berrios and Kikuchi get their s*** together though. 1 of them figuring it out we're still in a fine spot. Obviously it would be ideal but you don't need 5 starters in the playoffs, and we almost certainly aren't catching New York. Having someone awful blow 1 start every 5 days is something that hopefully will be addressed but we can and probably will make the playoffs in spite of that at which point it's no longer an issue. Hopefully Berrios rebounds at some point. You either replace Kikuchi somehow internally or grit your teeth and deal with it. Playoffs comes and even if Berrios is average then Manoah, Gausman, Berrios, Stripling is a very good playoff rotation. Getting a couple pen arms is way more important.
Obviously if if costs us a playoff spot that's a total disaster, or if neither of them can figure it out something for sure has to be done. I assume we'll have more clarity come deadline of just how much of a lead we have on Cleveland and plan accordingly, but if you're 15 games back of New York and 7 up on Cleveland upgrading the 5th starter is almost a fools errand. You're going to be a WC 98% of the time at which point your acquisition goes to the pen or isn't on the playoff roster entirely. Just upgrade the pen and stand pat elsewhere at that point
