This current group of, Dozier, Plouffe, Arcia, Hicks, Gibson et all has done nothing but lose since they have come up to the big leagues.
It's been pointed out before, but Arcia just turned 23 in May and only has 550 or so MLB plate appearances. Let's give him some actual time to develop. If by the time he's 26 and still hasn't come around, then I think it would be more fair to heap blame on him. The same can be said for Hicks.
Also, I disagree that the way to put together a winning team is to dispense of young, high-upside talent under team control for several seasons by hitting reset and acquiring different prospects. Prospects don't win major league baseball games--major leaguers do. Let's see what we've got before abandoning ship.
