Rafaela's "value" will exceed what they pay him, but what they'd actually pay him in arbitration and FA would be the same or less IMO. For there to be cost savings with Rafaela, he'd have to be a 110 wRC+ guy or something going forward. Good glove guys just don't get paid.
Bello's contract is fine if you think he has TOTR upside. I think they thought that at one point. Right now, he has 3rd starter upside. With injuries these days, you don't extend 3rd starters.
The Anthony deal seems fine. He's going to be given a few years to figure it out and he wasn't really given enough protection in the lineup. It was really disgraceful that they put him out there and made him be the man from day one. Unfair.
