It wasn't a bad contract per se. Pitcher contracts are always risky, but the dude was coming off a World Series MVP and even though he had missed time with injury plenty of times before, those prior injuries couldn't have predicted this. It was just bad luck.
I mean, I get what you're saying but I think LOTS of people could've predicted this, either via statistics or plain old "injury-plagued/cursed" gut feeling. I don't really care because 2019, and as you said pitcher contracts are always risky, but still.
Stras will forever be a huge part of Nats lore, but he's done now, I thank him for his service and wish him well in the rest of his life - let's not forget he's still got a lot of that ahead of him
