Yeah, weirdly it's the fact that the gamble is basically entirely predicated on his health that sells me on this. The downside to this deal is still not really a big problem: he gets another bad injury and then is around as a veteran leader for the younger IFs.
Obviously, if he does get hurt, the depth is pretty much nonexistent, which is why I'm seeing various rumblings about wanting another SS as further depth, and while in the abstract that's a lovely idea, it's totally unrealistic. Fact is, Newman has been a top prospect for a while, and has shown some good things in the minors. His ceiling seems to be more clearly a backup utility player, but weighing in too decisively on a small sample size is also bad when the player struggles somewhat. He'll get some chances next year, and even though Tulo's health makes it a bigger gamble that he'll be thrust into the spotlight sooner and in a bigger role than anyone would want, I think it's the right kind of gamble.
As I've been saying, I'm still totally fine with Ahmed, but there are real questions there, and the upside seems to be Mercer's bat with much better defense. Galvis maybe splits the difference and is the safest bet, but part of the bet with him could be that Newman or Gonzalez force the issue and make him a pretty expensive utility bat. With Tulo, you hope that he can replicate the role that Freese played here. It just seems to work for all sides.
An idea I've seen kicked around Pirates twitter which I do like is trying to nab Flores as someone who can come in and backup all the IF positions. I like the idea a lot, as it gives another RH bat with some pop, but I think Gonzalez would basically be ticketed for this kind of role. Whatever we do at SS, I expect it to be the last move involving the position players, with us then shifting to pitching. Luckily the relief market has been glacial. I'd be totally happy to nab Diekman and then take a run at getting Sonny Gray for the rotation (here's an unlikely-ish scenario, but maybe the Yankees would be interested in Gonzalez and a prospect if they don't sign Machado).
