IMO it is weird people were even expecting them to sign similar deals.
Soler has had one great year, one okay year (2023) and then a bunch of useless seasons. He had to hit 36 homers to be a league average player in 2023 because everything else is so bad.
Teoscar has 70% more career WAR in 60 less games. Since he became established, he has never been bad. His "disappointing" 2023 was as valuable as Soler's "strong" platform 2023.
If nobody was offering Hernandez a good enough long-term deal for him to even consider, then Soler's market might be ugly. I am looking forward to him signing an incentive laden 1 year deal with Toronto. Maybe a cute little 2 year deal with little risk. Some team options for fun.
Now, Hernandez is simply so much better that he can reasonably try to have an elite 2024 and then get a Castellanos contract. Soler would be a fool to do that and should take the most guaranteed money he is offered.
