Nick is only going to provide $800,000 of offset at this point, though I suppose he might sign a deal with incentives that could raise the number later. We can't get a decent catcher for less than $4-6 million and 8-10 would still be better. Caratini made $6M last year and given how scarce catching is might beat that as a FA. Rutschman makes $5.5 and will also have a high trade price. Vasquez made $10M last year and is probably still good for five.
I give up the 2nd and the 5th if you could both find a better catching option and sign Bichette for 3-5 years, but you can't, in either case.
I hear you on the bird in hand being worth more than a draft pick especially with this team doing the drafting, but you have to give Miller a chance and if 2024 Bichette comes back he's not even better than what we already have. He's a very poor defensive SS too (the Castellanos of SSs) too so simply moving him to 3B or 2B doesn't mean he'll be great there either.
And 2027 isn't a long way away. It's one season away. Albeit a season that might not be played until June or July.
