I feel like the idea almost everyone is missing is this:
We have a decent bullpen right now.
I can already hear the sneers and loud protestations. I understand.
But we have a decent (read average) bullpen right now.
It doesn't feel that way because we had a truly, legit ELITE bullpen prior to the trade deadline last year.
Don't be mad we haven't replicated last year's opening BP potential. Be happy we got a whole lot in trade for last year's pen and now have what really looks to be a new serviceable one.
That, with a (hopefully) great starting rotation and a probably average offense could win quite a few games this year. Also, don't discount the bump most teams get with a new coaching staff.
