Hard to claim Cowan is a better choice than Bonk, since Barkey's performance is pretty similar to Cowan on the same team.

They do want certain skill sets, speed, IQ and work ethic seem to be at the top of their list.
Any team that drafts York, Brink, Andrae is not fixated on size, but they do want balance.
