A "bit" disappointing is an understatement. They spent nothing. This was the year they were going to swing for the fences and Juan Soto is in a Mets uni. They didn't have to do that but they could've spent. If they aren't going to do it now its never happening.
there are two separate questions: has the team improved vs did they spend for a premier FA? I think the answers are yes to the first and no to 2nd, and I sort of don't mind no to the 2nd, especially w/r/2 position players.
There's no real question that Lowe is an upgrade over what we trotted out at 1st. He's a good ballplayer. A full year of Crews should be an upgrade over Thomas, who really gave us only 2+ months of positive play (he stunk in April before his injury and only took off when he was back). Wood could play left in a wheelchair and still be an upgrade over Rosario. Ruiz is due for a dead cat bounce, and 3rd would be an upgrade even if it is replacement level. If it's DeJong, then at least the left side d is better. If CJ Abrams is your concern, then you are in good shape. Would I have liked Santander or Pedersen or others instead of Bell? Yes. Is Bell better than Meneses? Likely.
I think they missed on pitching a bit. I am ok on t h e rotation quantity-wise, but there were some lead dogs I might have liked. Not to come up with a hi-lev reliever is a problem, but let's not overrate last year's high wire act. Let's ease up a bit on trashing this team because there's no Pete Alonso or $50 million committed to a SP.
