We have the father sons, all the Lions need now is the brothers rule.I've seen plenty of young Tom Berry here, kid's as hard as a cat's head and never, ever takes a backward step just like his brother Jarrod....though just like pre-draft 2016 I still think you underrated Jarrod then, and still do. The reason you may have underrated Jarrod might be because you were unaware he virtually had no pre-season recovering from surgery and then had some injury issues early in the season and never really got going until late in the year.
I was always confident Jarrod would play AFL midfield even though he had limited exposure in his draft year due to fitness and injury, late in the season he played several games in the midfield and absolutely killed it. Very significant that he's played the majority of the season for Brisbane in the midfield and 2 weeks ago Chris Fagan gave him the job on Joel Selwood who he restricted so well that the Coach rapped his shut down job in the after match presser.
I'd also strongly disagree on Tom being more athletic, Jarrod would have him covered there and whilst he may have better all round foot skills he certainly doesn't have the penetrating long kick Jarrod possesses. Like you I think Tom is very talented and has all the requisites to play AFL midfield...the standout quality being his hardness in the contest.
