I think the issues with Swanson are relatively modest, yellow flags more than red ones. The arbitrary endpoints game is stupid and something I thought we were smart enough to collectively move on from over the last 5 years or so.
His xwOBA this season is .324, above league average in the 54th percentile. He's underperforming his xwOBA by 51 points, for his career coming into this year he'd underperformed his xwOBA by 10 points. So you would say he's luck-neutral been a roughly league average hitter, which is not all that far from where we expected him. I don't love the elevated groundball rate, though he did that early on last year so I wonder if it's a thing meant to combat the April conditions at Wrigley.
The defense is down. but I'd pump the brakes on getting worked up over that. Largely because 1/4 a season of defensive metrics is little more than an RNG. But also I'd be curious to see what it rates at since he came off the IL. He had a rough few weeks there in April, but I feel like he's been largely back to normal since? I'd also love to get splits on his running speed, that's down YoY and also something I wonder if we blame on the knee injury.
Like I get the hand-wringing because Swanson's line is ugly, but looking under the hood there’s just not much to be alarmed about. Certainly not enough that I'd be doing take backsies on his nearly 5 WAR last year.
