Callow wouldn't get eaten, on the lead his speed is great, he's so smart in using his body and his hands are so good he is naturally able to win contests and having his hands are a bonus.So you didn't read much of my post then?
Brian Lake was drafted 20 years ago. He was a run of the mill defender for his first 150 games at the Dogs, he regularly got a pantsing. Would Callow be afforded the same amount of time? No. You are remembering Lake for his last 50 games of a 250 game career.
McGovern has barely had an opponent for the last 6 years and he's one of the best intercept marks in history.
As I said, he would have to be played as a loose defender in a spare behind the ball system like WCE deploy.
He's not a FB and never will be, he would get eaten alive by the likes of McKay, King etc moving forward, not only on the lead, but also trying to defend them when out of position.
You have disregarded the Div 2 carnivals as irrelevant in the past, also the TSL when it came to Tarryn Thomas, you can't suddenly use it now as evidence as to Callow's body of work...
