I don't really see the bottom of the rotation and the bullpen as areas of great need, assuming Nola is re-signed or replaced in an equivalent manner. Walker #4 Sanchez #5, a couple of depth pieces (swingmen or minor league deal vets) but probably not anyone of Lorenzen's caliber or higher (assuming those guys are all >$10 million and 2-3 years.
The pen, yeah, they will probably bring in one veteran arm to replace Kimbrel as well as the usual assortment of upside acquisitions (which has already begun) but assuming they tender Soto and Kerkering makes the team there's really only one high-leverage opening and one low-leverage spot (which may or may not still be Covey's, but if not it surely won't be anyone on a guaranteed contract/out of options... unless it's the 6th starter candidate).
I'd still change the entire bench, if the three starting OFs actually are the same. Replace Pache with a corner OF RHB and replace Cave with a LH bench bat who can play both 3B and LF. If that guy can't play 3B then replace Sosa with a LH utility guy. Clemens technically is that person but not that exciting, offensively or defensively (especially should he be forced to play SS).
Dombrowski tends to make big moves and they are unlikely to be in free agency this time (other than the starting pitcher but maybe not even then if it isn't Nola) so we'll see how serious he really is about listening on Nick and starting Rojas in the minors. Either or both of those things dictate moves. Neither means it's the same line-up as last year (since Rhys didn't play) and that might be okay too. But better to spend a little money on free agents than be stuck trading prospects at the deadline.
