Kimbrel has only blown 2 saves the entire season compared to Hendriks now 6. And that lead he blew he pitched in the 8th where historically he's been worse than the 9th. I'd much rather take my chances on a future hall of famer.
Kopech has always been a hot head. Saw it in the minors. I'm actually shocked it took this long for him to get that fired up with the ump. He'll learn though showing the ump up. Some umps out there would've tossed him with him doing that.
