By no means am I giving up on him, and it's been insane on twitter the last week or so seeing people suggest he's a total bust. He's a guy that WAR should love due to his best skills. I'm way more concerned about Kopech's struggles, to be honest.
With these young guys, I feel like there's a difference between being frustrated and concerned. When Collins wasn't swinging at any pitches to start the year, that was frustrating. On the other hand, Giolito would be a concern due to lacking really any true major league qualities.
