No, but ultimately, you have to choose between keeping someone under team control or acquire someone else.
A GM can't be blamed for not acquiring as many "under-the radar" RP'ers, if it was because he had more established ones to keep than the other situation being compared to.
That's why I was wondering what his success rate was with the Rays.
We all know they had good pens, but some was aided by pitching more innings, many times with a starter getting relief innings after an opener.
(I'm not doubting that Bloom did better with the pen when with the Rays, but there is a lot of context needed.)
