No way. You undersell these guys way too much. 50th percentile is:
-Orelvis an average everyday 2B. Value comes more from the power side and less on the glove side. 2 WAR kind of guy.
-Schneider probably the same. Low average, high walk profile. Also a 2 WAR kind of guy but he already projects for a good amount more than that.
-Barger and Jimenez would be low end regulars or platoon/utility players.
-Roden and Horwitz would be platoon players or bench players. These guys are your 50th percentile 0.5 WAR types but they bat lefty so they can be useful. But then again they are ranked 18th and 19th in our system so whatever we get from them is gravy. Steamer loves them though for whatever that is worth. Your Orioles start guys at 1B and DH that barely project to be better than these two, for example.
