He seems to be saying that the new smart bet is in undervaluing RP's, in not paying through the teeth for their mercurial arms, and in investing such savings elsewhere.
Are Kuma's 170 innings of 3.00 ERA the purchase we made with the savings we accrued by signing a bunch of spaghetti (against the wall) bullpen arms?
It is worth looking at it that way, to some degree.
The other bet here is that you can pick up decently decent RP's all the time, as the season moves along, giving up down-on-the-farm-boys who are not your most electric prospects.
The GM gets early grades of "A" for each of the Karns, Miley, and Lind moves. Martin's inking gets an "I" at this point, trending toward a "B" when I believe his (now healed) wrist made all things bad and he really does wear Paul Blair's glove and swing a bat with a bit of sting. With all that bought, the pollyanna in me is willing to trust Dipoto's got the bullpen thing covered. Well, until his BP pours gasoline on our May-June hopes.
