That would be something like the best 23 if they were all fit and firing. Only Martin, Prestia, Lynch maybe Broad are on the final stretch of their careers. Those marked with x and bolded have missed strings of matches with injury, all bar Balta of those basically having most of the season wiped out.
Other notable players seasons wrecked by injury: Grimes, Clarke, Young, Naismith
McIntosh not selected in this team, 29yo double flag player.
If you think if that team largely takes the field fit all season and Richmond are still finishing bottom 4 it is you who is deluded. There are weaknesses within that team but no more than most best 23's carry. And there are some serious weapons there that can hurt any team. There are 12 players bolded in that team and say leave Balta out of that group the rest have more or less had their seasons wrecked by injuries. That is half your best 22 including the majority of the most important players.
Players not named in that team above have played about 150 games between them this year, so far. That is about 8 every week on average. But it is not like it is the best 8 playing most of those games due to fringe players being injured, those games are spread between 18 players.
Whether any or all of those injured players are in some sort of terminal decline is speculation. All clubs have a couple of older players dropping away most years. But plenty of players in the last half or third of their careers come back from serious injuries or niggling issues.
If that team I named had an injury run say like Geelong, Hawthorn, Fremantle or Swans this season, how many games do you see them winning?
It's a really poor midfield lacking in speed and foot skills, and your wingers are no better. Players like Martin, Pickett, Prestia, McIntosh, Grimes are shells of their former selves and you're expecting performances of yesteryears which they are just not capable of anymore. Gibcus, Miller, Ralphsmith, Brown, Lefau, Mansell and M. Rioli is a seriously large group of players yet to play 50 games if that's your best 23. 32 year old Marlion Pickett is the only player in that entire team who has played between 50 and 100 games which is a seriously gaping hole in your list. Lefau and Brown are encouraging first year players, and Ralphsmith has improved, but none of the others have seriously proven they'll be reliable long term players.
I've noticed you left out Bolton, and even including him at the expense of Mansell and Ross to sub, it's an uninspiring team.
