To me this is a comment on mechanics.. Palmer said Josh has ownership of his stroke and doesn’t have to work on throwing consistent spirals anymore, not working on hitting certain spots over and over again.
But take it however you want to take. Josh does throw some on his own time I’m guessing, most likely after mini camps. But that’s me guessing. Josh says he still throws a little in the offseason.
Maybe “work as hard” is a bad phrasing, sounds critical. “Does less work” is probably better phrasing. 😉
Mahomes hosts WR camp every year for comparison. But that’s Mahomes, it’s not for everyone.
