Allen wasn't very good last year, but I'd still be interested. Proven is kind of a subjective word in this case, but of the guys most people would think of as "proven" Familia, Robertson and Soria were the only relievers who I am disappointed we didn't/couldn't get. Those are the big names that as far as I can tell were still productive last year, are still piling up strikeouts and apparently at full health.
Not that I don't want other relievers, just that my interest in all the rest vary and may not line up with perceived value. Buy yeah, if Parker is the best we do for the pen this year, I'll be pretty resentful.
I was also really hoping for Familia, Soria or Robertson. Still kinda upset about Robertson in particular after what he signed for. Would have taken any of those three and been pretty darn happy.
I'm pretty high on Cody Allen despite a down 2018. He just turned 30 in November. Career ERA of 2.98, (5 straight season's previously of an ERA under 3.00), career AVG of .217, career WHIP of 1.19, 3.26 career K/BB. Six straight season's of 67 or more appearances and IP. And those numbers include a down 2018. I just think he's a perfect fit unless there is some health or sudden velocity concern I am unaware of.
Holland has been mentioned, but he's 3 years older than Allen, their career numbers and quite close, but Holland seems to be on a 3 year downward trend except for his late seaskn surge with the Nationals last season.
I'm fine with Parker as a piece. Now give me Allen with all of the other pieces on hand and I'm actually pretty optimistic.
