I'm sure it's not 200 either, I'm just curious as to how big the gap really is. Morgan is definitely not a crappy hitter. He's got a career OPS of .747, and it's very OBP-heavy. That's valuable. Dunn loses as much non-OPS related value as a player can possibly lose. He plays a high-offense position (although weirdly, CF is pretty much playing even with LF this year in the NL) and he plays absolutely awful defense. He even strikes out so much that you can shave a run or two off his value (at the stathead rate of about .02 runs per K). I'm guessing Morgan's steals aren't optimized to high-leverage situations, so his 30/14 is pretty close to breakeven. Going by VORP, the difference between Dunn and Morgan to date is 27 runs on offense, which I believe includes a positional adjustment and proper weight to the Ks. So how much of that 26-run gap can defense close? I don't have an answer, but I'd like something better than "MLB teams would be doing it if it were right," because it took those same teams decades to learn to properly weight OBP, which is pretty easy to measure, so I have little faith in them measuring the value of defense properly. And the Cubs' situation is slightly different, because they don't have anyone they are willing to replace in the OF. I'll settle for saying Nyjer Morgan and Adam Dunn are as close in value as two position players with 200 points of OPS separating them can be.
