You said this:
"I'm not sure if people get the idea of what depth is..."
Do you really think 'people' don't grasp the idea that pitchers are fragile and having adequate backup is a good thing?
The real issue at hand is whether the 2018 Red Sox began the season with sufficient depth. We don't really know the answer. But you could probably make a case that Johnson, Velazquez and Wright look like a semblance of reasonable depth. And if it turns out that more is needed, there are some other dumpster dive options out there as always.
I think it's probably a combination of things. He's healthy, he worked hard in the offseason and added a little strength, and as you say his approach seems better and more aggressive.
Fun to watch, that's for sure!
I disagree, I thought Farrell was generally fine with how he handled the pitching changes.
As far as looking strong is concerned, Sale looked strong as an ox in that game he reached 300 K's. But in retrospect it might have been a good idea to pull him sooner.
A lot of it's always going to be guesswork anyway.
Every team in baseball history has been susceptible to pitching injuries.
With regard to whether the Red Sox have 'enough' pitching depth, you need some sort of comparison point. How does our depth compare to that of other contending teams? How does it compare to that of other Red Sox contending teams of the Theo Epstein era?
OTOH, maybe your comment that our opening day rotation was 'pretty bad' because it included Johnson and Velazquez for a start or two was overblown too...
Don't you think the pitcher's goal in general is to make a really tough pitch to hit - the batter is either going to miss it or if he hits it it's going to be weak or glancing contact.
I have never said the Moreland signing was a great one. I just didn't think it was a horrible one. He got a Chris Young contract to be a backup/insurance first baseman.
I think it's time for me to start my thread about Baseball Philosophy - in which we seek explanations for WHY there is so much randomness in baseball, WHY hitters and pitchers have such hot and cold streaks etc.
