I don't think so. he has been stuck in the forward pocket this year, and is not contributing as much to the team as normal.
Plus he is not known for his tackling.
Bolton is absolutely a dynamite forward pocket if played there. The fact he is an elite centre square player is a bonus, it doesn't detract from his forward ability. Pretty pointless using his output this year in a wooden spoon side while he has checked out and the coach has been using him as a pseudo KPF target (not a proper small forward role).
And tackling doesn't define forward pockets. While it's nice to have a Ballantyne type, it's not common. Papley, Cameron, Stengle, Hill are in the same realm as Bolton with a lack of tackling. It's not their main game. They are primarily there to kick goals.
And pressure is more nuanced than tackling and chasing. Having an opponent that is shit scared to leave your side helps. And natural crumbers can get to the fall of the ball and get a possession or stoppage.
