Sure, because to this point he's had an OK year at best, and, as pointed out, he's been a disappointment this season relative to expectations. Yeah, it's great his ERA has been trending the right direction for a while now, but it's not like anyone has to dig deep to see where he's struggled or been noticeably worse this year. Like, I'm much more encouraged if he stops walking so many guys (and he did that last night, huzzah!) and gets that walk rate and WHIP down than really ever worrying about his ERA. He's walked 3 or less batters every game in his last 9 games and 12 of his last 14 (2 or less in 9 of those). He's largely been the same pitcher he's always been going back to late April. saying he's walked 3 or fewer batters every game is a lot less impressive when you see he's walked at least 2 in every start since april. he only has 1 more strikeout than walk in each of his last 7 starts. his flip/xfip was 4.63/4.28 in may, 4.69/4.21 in june. and 5.38/4.98 so far in july. has has .6 war in 18 starts after averaging like 4.5 over the previous 5 season. it's dumb to say quintana has sucked or whatever (i was one of his biggest defenders on here in the second half last season), but it's pretty easy to see why there has been some disappointment. there's a significant difference between quintana's 2018 and the rest of his career.
