Right now, DiamondView seems to be at peak value:

2. Recreating The Tribe - It's clear that Coonelly wanted to use the Indians as the model for the Pirates. Huntington certainly knows how the Indians work, but can he actually find the parts? The Indians have a dynamic GM, solid scouting, a great stats department, and the wild card of the DiamondView system. I've been told that one new GM asked about acquiring the system and was told he'd need to deal a top-level prospect for it. It's time to start wondering what D-View could fetch on the market. Sure, PECOTA likes him, but traditional scouts don't seem to give a damn. There's no way we trade with a division rival, so the Royals might be an option.
