I can suggest this because this is exactly what Dimma has said he did!You cannot claim Vickery was 'gifted games' in comparison to Griffiths. Vickery did more to earn most of his early games than Griffiths did - let's not forget Griffiths was rushed into the side immediately in his first and second years without having any VFL form on the board first. The difference between the two is that Griffiths didn't do enough to stay in the team after that, whereas Vickery had become an important part of the team by then.
Back in 2010, Hardwick said he wanted to get as many games into his young charges as he could. This included Vickery. You forget that Griffiths had two shoulder reconstructions in his first two years, one of which included bone grafting. Ben has only been free of pain for a couple of seasons. Vickery already had a season under his belt too in 2010.
Vickery has never starred in the VFL on any regular basis to demand selection. This is another clue showing he was gifted games. Even this year I watched him play VFL and although his write up was ok, I thought he was ordinary. At his senior level, one would have expected him to dominate, but he did not get remotely close to doing that.
