They also gave over $300 million to a couple guys who get injured all the time and don't eat innings (Snell and Glasnow).The Dodgers can’t do anything about their pitching except hope they get healthy.
The way high velocity is prioritized these days, you’re only going to see more injuries at a position that is inherently injurious.
You can’t spend your way out of that other than to just stack talent, and that has its own limits.
Still, they’re leading the division so I don’t see any reason to panic. If people are freaking out because they aren’t on pace to win 110 games, they’re fools.
