I don't think there's anyone you lock up at this time. Too many question marks. I could see Villar if you believed his 2016 was his true self. But there are signs that some regression is in order. Plus, you want to see him improve his defense. Broxton, Santana, Arcia, Shaw, Perez, Susac, Bandy, Knebel, Anderson - they either need to show they are long term pieces - or they just aren't that good. None of these guys combine talent and production that warrant a long term investment. Guerra is too old to sign to a long term deal - even if he keeps pitching well. We control him through his mid-30s already. No issue there. Peralta, Nelson - way to volatile. Peralta could be a DFA if he tanks this year. The one guy on the team that I see as being a solid, everyday player is Davies. I don't see a great player - but a solid guy. That said, he's not a great player - and I don't think he ever will be. No point in locking in a good - but not great - player for extra years.
