I know people give Huntington a hard time about drafting, but I don't think people look as deeply into it.
2008 - Alvarez
2009 - Sanchez
2010 - Taillon
2011 - Cole
2012 - Appel
2013 - Meadows/McGuire
2014 - Tucker/Joe
2015 - Newman/Hayes
2016 - Craig
2017 - Baz
2018 - Swaggerty
2019 - Priester
Sure, Alvarez didn't turn out. That's partly most likely due to the Pirates rushing him to the Majors. Tony Sanchez didn't work out either. Taillon is a very good pitcher when healthy, the guy's just had bad luck. Cole was good, but he's been fantastic in Houston. I think the disconnect between Searage and talented pitching starts to show here. Glasnow literally admitted that he didn't listen to the coaches here, it seems like it was a good thing, that or Tampa knows what they're doing. Trea Turner was a Pirates draft pick in 2011, the guy didn't sign.
I think overall, Huntington has done a decent job of drafting, if I needed to grade it, it'd be a C+. That said, there have been very questionable moves by him. I think it starts with trading Charlie Morton. I know a lot of people didn't care when Morton was traded, but at the time, I was wondering "why?". He didn't have the greatest season in 2015, but in a rotation where Burnett was retiring and Jeff Locke was somehow still in the rotation you trade a guy who's had a solid 3.5-3.7 ERA the previous two seasons, then sign Vogelsong? Seems like a bad tradeoff.
Then there was the trade involving Liriano to Toronto, where they gave up Reese McGuire and Harold Ramirez for Daniel Hutchinson. An absolutely bizarre trade. If it was a salary dump, why trade two of the top prospects in the organization? Then of course, Huntington's death throe was the Archer trade. Glasnow, nobody could really see that coming, the dude was absolutely mediocre during his time here. Meadows and Baz however, that was hard to swallow. I understand your point about Hurdle not playing Meadows and I understand the Pirates wanted an ace-type pitcher to replace Cole, but why Archer? Archer was basically all the negatives of Cole, without any of the positives. Had the Pirates just traded Glasnow and Baz, it would've been much more tolerable, but to trade Meadows is ridiculous. I'd be a lot more optimistic if we had an outfield of Reynolds and Meadows heading into 2020.
