I glanced through the list of 1st round and 2nd round picks by the Pirates. Not a very illustrious bunch, apart from the unicorn Skenes. The catcher also drafted 1-1, Henry Davis, has yet to pan out - as with another 1-1 pick of our local acquaintance, a succession of injuries may have sapped his talent. A guy you'd maybe never heard of (I hadn't), Carmen Mlodzinski, might be ready to provide significant value going forward at age 27. That's about it in the past decade-plus (and granting as always that maybe very recent picks will have altered the trend) - Ke'Bryan Hayes almost came through but wound up fizzling. I suppose you could reach back to Gerrit Cole as a draft success, but he was traded in 2018 and none of the talent they received in return was much of a factor one way or the other by the time Shelton appeared on the scene.
Poor choices on draft day, or poor development in the minors, or poor coaching at the major league level with the manager to blame?
"Yes," I suppose. 😄
