17 homers in 64 games makes it hard to imagine him being less than a 20 homer guy over a full season. Especially for someone with his feel to hit. If he can bat .280 with 20 homers and play average defense, he’s a star. If he can bat .300 (very possible) with 25 homers also very possible based on this year) he’s an mvp candidate. Let him catch for 5 years then reevaluate moving him to 1st or dh to preserve his body and bat as he approaches 30
Boras also might not like the idea of moving him off of catcher prematurely as it would limit his earning potential
