It might be a bit unfair, in particular re Weitering. It's something I've picked up on but I haven't gone back to corroborate it.I think this is unfair - I've heard Weiters praise Young so that part is at least not true.
I do agree though that he is not best 22. Just like there is forwardline chemistry, the synergies between the backline is important too.
Young:
-as an individual defender is solid
...great length, height and decent speed
...reads the play well and takes a lot of intercept marks
...poor body work and doesn't have a strong enough lower body to hold his own in a wrestle
-as a team defender is average to poor
...will often get in the way in a pack mark situation preventing Weiters from doing his thing
...doesn't put on blocks
...doesn't communicate or work well with the other defenders
-with ball in hand is atrocious
...slow, like treacle slow
...poor decision maker
...poor kick
McGovern and to a lesser extent Kemp have much higher football IQs than Young. Young's sole benefit compared to those 2 is that his size is a better matchup when we face a team with 2 monsters (ala Geelong, Brisbane). Literally everything else Young makes us worse.
I agree with your assessment for the most part, though the cons far outweigh the pros, to the point where I believe playing him is detrimental to the team. Similar to Parks in that regard, though for different reasons. As harsh as it is, it's hard to carry players in a team defence who aren't predictable to their teammates and can't be relied on with ball in hand. It got to the point where teams would intentionally sag off Young from kick outs in the hope that we would kick it to him (which we regularly did, to my eternal frustration).
