I don't think that's the case at all. The 2019 squad started the season with Sano, possibly their best slugger (though everyone's so good right now it's almost a moot point), on the IL. Later, they had their two best overall hitters (Cruz and Garver) go down for a few weeks each.
The team played some of its best baseball during that stretch of play.
If a pitcher goes down, things could get ugly, but thus far the team has weathered some really good players spending extended time away from the field and no one missed a beat.
yeah, this team is a lot deeper than that team was... wasn't Lawton traded that year too? or am I thinking of 2002?
I'm not even worried about a starter going down for a couple weeks. Smeltzer has shown he can step in and be competent... Multiple starters though... that's worrisome, and the pen scares me more and more as the season goes on.
