If Jacobs can show that he can catch full time and be decent at it, then Stokes should get a nice shot at 1B.
Mike has shown the ability to adjust to pitchers as they adjust to him. After hitting 4 HRs in his first 4 games, he went into a mini-slump then made adjustments. Then again, pitchers adjusted to him. And somehow, he was able to come back and finish the year hitting .310 with his 10 HRs in around 100 ABs.
So I think he's the real deal. But not a catcher. No way. He's an adequate first baseman. He looked like Keith Hernandez compared to the failed Mike Piazza experiment at 1B, but he's not that great a fielder. I'd call him adequate.
Look, after you guys win again in a few years and dismantle your team again, you can always trade Jacobs to the AL where he can shine as a DH.
And Petit is no throw in. He's a legit prospect that throws slow stuff but manages to average a K an inning.
