Jacoby Ellsbury was 24 when he debuted and collected his first 100+ plate appearances in the Major Leagues. Adam Jones was 21/22. As it stands, Jones is two years younger than Ellsbury and every bit as good overall as a player.
While Ellsbury may get all the attention, Jones is just as good now and - given his age and skillset - in line to be the better of the two down the road. By a pretty fair margin if his power comes back. The return of Jones' home run ability would dwarf the slight advantage Ellsbury gains by being a better baserunner.
Boy did we ever make a mistake. And also fuck the hype machine.
