I'm not a fan of dealing for RPs, generally. Hoffman, for example, was awful after being traded last year.
OTOH, I don't love HS pitchers as a rule....but I still don't love this deal.
The bullpen looks well set up this year and next, though.
They'll need to find some hitting and D next year.....and if there is a long lockout, next year isn't likely worth much.
