I like what I have seen so far from Barber. Of course my thoughts are probably shaped a little more by national consensus rankings than my own observations, and the only way to tell if Barber was right is to wait 5 years and assess.
The UDFA strategy is not just wise re the cost of middle relievers. It seems to be a wise reaction to the contraction of the minor leagues and the reality that there are no at bats to hand out this Summer. One can be opposed to the contraction of the minors as I am, and still see the wisdom in this player development strategy.
Barber does seem to fall a little more on the tools side of the tools versus polish argument and that is another area where I like what he has done independent of any rankings. I always err on the side of tools when given a choice because we can find replacement level players if we work hard enough at it.
