No disagreement about sample size, which is incredibly small. So of course there is hope.
On the other hand, we know for a fact that Price's lifetime ERA is 3.24 but last year it was 3.99, which was his highest season ERA since his first year, 2009. And this year so far--granted, a small sample--his ERA is 5.09. So it very much seems to me that the burden of proof lies on those who say, "Price is just as good as he always was."
Another thing about Price worries me. He seems to love his fastball almost as much as opposing hitters love it. It's his go to pitch, which means those hitters can sit on it whenever he is behind in the count. On top of that, as we saw last night, he now seems to be using other pitches--especially changeup (essential for a lefty who normally will fact 75% or more righty bats), but also curve and slider--but he can't put them where they will do some good. Those breaking balls seem to alternate between being up in the strike zone and close to the center or so far outside the strike zone they are not tempting.
If you check the speed gun results usually displayed on the TV screen, you will notice that Price seems capable of consistently throwing a 95-96 mph fast ball, which is excellent. Normally, usually, he can also spot it (if not all the time). The problem is that no fastball by a starter is good enough to rely on solely for 6, 7, 8, or 9 innings. You must be able to keep batters off balance with a mix of pitches that go to the right places in the strike zone or close to it. Since he came to the Sox, I have not seen Price do that.
