I dunno, I reckon if you get a guy to 294 you find a way to get him to 300. Still irks me that Campbell was left on 297 somehow. (I don't remember the details.)
I had a look at Shedda's game stats for season 2019 and it's chalk and cheese with 2022. He was getting high 20s for disposals, laying big tackle numbers, hitting the scoreboard, getting clearances. I don't know if he has a Zimmer frame-friendly new role, but if it's less output from the same role then yes, he is cooked.
