You do not get to speak as to why his target weight was anything. All you have posited is that he felt faster are 320 than he did at 350. You have zero basis for that assertion.
You seem to not understand the difference between physical development and technique development. There is no reason a 24 year old could not learn how to refine his swim, club, rip, placement, etc technique. He has improved in those areas for the past 3 years but magically he stops at 24? That is just stupid.
And as i said before, this reminds me of the Bosa debates several years ago. Then too I was told that I am imagining athleticism that is not there. I was proven right then. I am fine with allowing reality to dictate again.
I have already been told that he is so slow that it is easy for the C to setup then I showed evidence to the contrary when he gets off on the snap.
