I think you're confusing "best 22" with anyone who got a game or was fortunate to be uninjured while everyone else was.Hammer, William, Gardiner, walker, Bastinac, shache, Keays, hipwood, bewick, lester, Clayton, dawson, n.robbo, Jansen, Taylor.
There's 15 who were all best 22 at one point or another during the year. I cannot see any of these guys breaking into any other team based on their performances this year. Not counting Essendon obviously.
