I have a hard time imagining what sort of already arrived MLB player they could get that would make it worth their while to deal him. The whole service time issue would be more or less a wash and then you'd be trading for the sake of a trade rather than resupplying the system as a whole. You'd likely be trading Barney's certainty for more upside, and probably at a different position. Barney is so valuable despite his lack of star potential because he's pretty well proven his ability to be average at worst(plus defense, .270 hitter in 900+ PA) with so many team controlled years in front of him. Taking on someone with more risk but more potential reward could be worth their while. I agree that it's not an easy fit, which combined with all that Barney offers makes it an unlikely match. This sums it up. Barney will more than likely be a productive, league average/above average player through his prime. However, if given the opportunity to move a guy who's a sure thing to be a good but not spectacular player for a package of high celing guys, you can't turn it down. If someone really wants him, and they offer a top 100 guy you take and run faster than Tony Campana. Basically, you're trading the promise of stability for the off chance of greatness.
