I'm not worried, yet. It's a small sample size. Corbin, Woody (provided it's a short IL stay), and Freddy have established themselves as among the best strikeout artists in the game. Same with Devin from the bullpen. He's only pitched 3 times thus far, which obviously impacts the overall K numbers. These guys are the reason why we've been among the top pitching staffs in terms of Ks over the past few years.
We'll see with guys like Lauer, Bush, Strzelecki, etc. Velocity concerns in the beginning of the season generally tend fade away the further you go and the warmer the weather gets, unless there's an underlying injury. I just find it hard to believe that all of those guys simultaneously have underlying injuries.
Trading a Hader definitely hurts. And the guys we've replaced him with (Payamps, Guerra, etc.) don't exactly have high K histories..
But, at the same time, you have Uribe, Cousins, Gasser knocking on the door in the minors...
