Yeah Swanson has that good hitter, bad plate discipline thing going on which you probably want to avoid after the Castellanos fiasco. They sure could use his glove in the middle of this defense, but this was a guy that was looking at getting non-tendered in the middle of the 2021 season because he wasn't hitting.
Turner is not a plate discipline savant himself, but with his speed and contact skills, you are going to get value that way and it adds another dynamic to the offense. Base running value too at least in the short term. If he's this athletic in his age-29 season, he hasn't really lost a step since he entered the league, it bodes well for his decline. I'm sure the Kevin Long relationship will play a role as well. I do wonder how long he will be able to stick at SS. He's always had that weird throwing thing going on, but he could probably play anywhere if they needed him to.
Correa is probably the best all-around hitter and the youngest so the upside for a long term contract is there, but I'm not going to pretend I know anything about his medicals. He was a top notch defender before this year before it fell off (at least by the metrics which aren't always reliable in SSS). He could slide over to 3B and not miss a beat offensively though if he had to. Feels like a Machado type.
Xander has always hit so he's probably always going to hit until he hangs them up, but he's had weird power spikes with meh metrics and he feels like a 3B waiting to happen for an already poor defensive team (people thought he was a 3B as a prospect so it's amazing he's stuck this long). Probably an easy pass unless the market is nuts.
Important to remember the new shift rules and how that impacts metrics. Some have benefited more from positioning than others.
I don't really trust Swanson on a mega deal. Between his 25%+ K%, meh on-base numbers, and him grading only a bit above league average as a hitter over a 4 year period (wRC+), it's just a combination of things which this team already has issues without real certainty you're getting an impact hitter. I fully don't expect the Phillies giving Correa a Seager deal, but with him and Turner, I at least would feel confident they are very good hitters.
Doesn't Xander have basic defense in The Show?
