Right, but Bellinger is probably a good example of this. Bellinger over his last three seasons has a 125 wRC+ compared to Pete Alonso's 128 wRC+. I'm using the last three because Bellinger was really bad four years ago, but it also eliminates a 141 wRC+ season from Alonso which increases his wRC+ to 131. Regardless, in those three years, the HR difference is stark: 78 for Bellinger and 118 for Alonso. Bellinger is far more of a defensive asset than Alonso. ZiPS also sees this, giving Alonso a healthy 138 to 121 wRC+ projection in his favor despite their fWAR being very close on that projection.
And yet, the difference in AAV between Bellinger (27m per year) and Alonso (31m) is just $4m. If we grade them on similar regression models, the .5 slip each year based on their most recent ZiPS projection for 2026:
Pete: 3.8, 3.3, 2.7, 2.2, 1.5 = 13.5 over 5 years = 2.7 fWAR average
Cody: 4, 3.5, 3, 2.5, 2, 1.5 = 16 over 6 years = 2,6 fWAR average
These two contracts are very close. Cody got an extra year, but he's a few years younger. However, when we look at the ask of each, Alonso is being asked to average a little more per year, but the difference in AAV is $4m. It's not a massive change. And on total value, it's a difference under $10m.
If we were seeing some league wide trend that players who gain value more through their bats, I think these contracts would not be so similar.
Bichette probably does not belong in this conversation, however. His contract is an opt-out heavy deal that very likely will be a one or two year deal with the goal to re-hit free agency. We should probably bin that one in a different discussion.
Overall, I think we may see slight biases towards home runs and offense, but I don't think there's some league wide trend where similarly valued players are being given significantly larger contracts. A few million AAV might be noticeable here or there, but even at $4m you're talking like the difference between a Hoby Milner.
