I don't completely know the DH rules, but is it possible to Start Morel at 3B and Player X at DH, then later in the game, sub Madrigal at 3B and move Morel to DH?
He has a tendency to throw flat-footed/off his back foot because he has such a strong arm, but that's terrible mechanics that won't translate well. Someone needs him how to step into a throw. There's a reason Patrick Mahomes is the outlier and not the norm in terms of throwing motion (because Mahomes is a freak of nature)
CJ Stroud is the outlier to the "never draft an Ohio State QB" rule. That school has QB after QB put up Heisman numbers against a scrub schedule, but most don't even get drafted, much less succeed. JT Barrett? Braxton Miller? Cardale Jones? Troy Smith?
