I think in part, this may reflect on the battle they had to sign Weaver. The word I've heard is that they intended to go after guys who were "signable" and in that regard, apparently certain of their picks were guys that apparently may not have the grades to go to a D-1 so the Angels are perhaps figuring these guys may be easier to sign, w/o the D-1 alternative as leverage.
Not certain if this is the "fact" just something I've heard about their strategy for this year. Curios if they selected anyone represented by Boras
